BATAVIA, IL and UPTON, NY – The world’s largest computing grid has passed its most comprehensive tests to date in anticipation of the restart of the world’s most powerful particle accelerator, the Large Hadron Collider (LHC). The successful dress rehearsal proves that the Worldwide LHC Computing Grid (WLCG) is ready to analyze and manage real data from the massive machine. The United States is a vital partner in the development and operation of the WLCG, with 15 universities and three U.S. Department of Energy (DOE) national laboratories from 11 states contributing to the project.

The full-scale test, collectively called the Scale Test of the Experimental Program 2009 (STEP09), demonstrates the ability of the WLCG to efficiently navigate data collected from the LHC’s intense collisions at CERN, in Geneva, Switzerland, all the way through a multi-layered management process that culminates at laboratories and universities around the world. When the LHC resumes operations this fall, the WLCG will handle more than 15 million gigabytes of data every year.

Although there have been several large-scale WLCG data-processing tests in the past, STEP09, which was completed on June 15, was the first to simultaneously test all of the key elements of the process.

“Unlike previous challenges, which were dedicated testing periods, STEP09 was a production activity that closely matches the types of workload that we can expect during LHC data taking. It was a demonstration not only of the readiness of experiments, sites and services but also the operations and support procedures and infrastructures,” said CERN’s Ian Bird, leader of the WLCG project.

Once LHC data have been collected at CERN, dedicated optical fiber networks distribute the data to 11 major “Tier-1” computer centers in Europe, North America and Asia, including those at DOE’s Brookhaven National Laboratory in New York and Fermi National Accelerator Laboratory in Illinois. From these, data are dispatched to more than 140 “Tier-2” centers around the world, including 12 in the United States. It will be at the Tier-2 and Tier-3 centers that physicists will analyze data from the LHC experiments – ATLAS, CMS, ALICE and LHCb – leading to new discoveries. Support for the Tier-2 and Tier-3 centers is provided by the DOE Office of Science and the National Science Foundation.

“In order to really prove our readiness at close-to-real-life circumstances, we have to carry out data replication, data reprocessing, data analysis, and event simulation all at the same time and all at the expected scale for data taking,” said Michael Ernst, director of Brookhaven National Laboratory’s Tier-1 Computing Center. “That’s what made STEP09 unique.”

The result was “wildly successful,” Ernst said, adding that the U.S. distributed computing facility for the ATLAS experiment completed 150,000 analysis jobs at an efficiency of 94 percent.

A key goal of the test was gauging the analysis capabilities of the Tier 2 and Tier 3 computing centers. During STEP09’s 13-day run, seven U.S. Tier 2 centers for the CMS experiment, and four U.S. CMS Tier 3 centers, performed around 225,000 successful analysis jobs.

“We knew from past tests that we wanted to improve certain areas,” said Oliver Gutsche, the Fermilab physicist who led the effort for the CMS experiment. “This test was especially useful because we learned how the infrastructure behaves under heavy load from all four LHC experiments. We now know that we are ready for collisions.”

U.S. contributions to the WLCG are coordinated through the Open Science Grid (OSG), a national computing infrastructure for science. OSG not only contributes computing power for LHC data needs, but also for projects in many other scientific fields including biology, nanotechnology, medicine and climate science.

“This is another significant step to demonstrating that shared infrastructures can be used by multiple high-throughput science communities simultaneously,” said Ruth Pordes, executive director of the Open Science Grid Consortium. “ATLAS and CMS are not only proving the usability of OSG, but contributing to maturing national distributed facilities in the U.S. for other sciences.”

Physicists in the U.S. and around the world will sift through the LHC data in search of tiny signals that will lead to discoveries about the nature of the physical universe. Through their distributed computing infrastructures, these physicists also help other scientific researchers increase their use of computing and storage for broader discovery.

At a recent physics seminar at the Department of Energy’s Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and has about six times the proton’s mass.

The observation of this “doubly strange” particle, predicted by the Standard Model, is significant because it strengthens physicists’ confidence in their understanding of how quarks form matter. In addition, it conflicts with a 2008 result announced by CDF’s sister experiment, DZero.

The Omega-sub-b is the latest entry in the “periodic table of baryons.” Baryons are particles formed of three quarks, the most common examples being the proton and neutron. The Tevatron particle accelerator at Fermilab is unique in its ability to produce baryons containing the b quark, and the large data samples now available after many years of successful running enable experimenters to find and study these rare particles. The observation opens a new window for scientists to investigate its properties and better understand this rare object.

Combing through almost half a quadrillion (1000 trillion) proton-antiproton collisions produced by Fermilab’s Tevatron particle collider, the CDF collaboration isolated 16 examples in which the particles emerging from a collision revealed the distinctive signature of the Omega-sub-b. Once produced, the Omega-sub-b travels a fraction of a millimeter before it decays into lighter particles. This decay, mediated by the weak force, occurs in about a trillionth of a second. In fact, CDF has performed the first ever measurement of the Omega-sub-b lifetime and obtained 1.13 +0.53-0.40 (stat.) ±0.02(syst.) trillionths of a second.

In August 2008, the DZero experiment announced its own observation of the Omega-sub-b based on a smaller sample of Tevatron data. Interestingly, the new CDF observation announced here is in direct conflict with the earlier DZero result. The CDF physicists measured the Omega-sub-b mass to be 6054.4 ±6.8(stat.) ±0.9(syst.) MeV/c2, compared to DZero’s 6165±10(stat.)±13(syst.) MeV/c2. These two experimental results are statistically inconsistent with each other leaving scientists from both experiments wondering whether they are measuring the same particle. Furthermore, the experiments observed different rates of production of this particle. Perhaps most interesting is that neither experiment sees a hint of evidence for the particle at the other’s measured value.

Although the latest result announced by CDF agrees with theoretical expectation for the Omega-sub-b both in the measured production rate and in the mass value, further investigation is needed to solve the puzzle of these conflicting results.

The Omega-sub-b discovery follows the observation of the Cascade-b-minus baryon (Ξb), first observed at the Tevatron in 2007, and two types of Sigma-sub-b baryons (Σb), discovered at the Tevatron in 2006.

The CDF collaboration submitted a paper that summarizes the details of its discovery to the journal Physical Review D. It is available online at: http://arxiv.org/abs/0905.3123

Ash River, Minn. – Construction begins this month on a cutting-edge physics laboratory in northern Minnesota, supported by the American Recovery and Reinvestment Act. Congressman James Oberstar of Minnesota and Congressman Bill Foster of Illinois today (May 1) are joining officials from the U.S. Department of Energy, Fermi National Accelerator Laboratory and the University of Minnesota to break ground for NOvA, the world’s most advanced neutrino experiment.

“This project is part of a bold, visionary initiative which will have profound implications for our understanding of the structure and evolution of the universe,” Congressman Oberstar said. “The billion-year-old rock formations in Northeast Minnesota are helping researchers unlock mysteries of the origins of the universe.”

The DOE Office of Science has provided $40.1 million in Recovery Act funding for the construction project. It will provide an additional $9.9 million in Recovery Act funding to Fermilab, which manages the project, for purchasing key high-tech components for the project from U.S. companies, enabling those firms to retain and hire workers.

Community members also are gathering in nearby Orr, Minn., for a public presentation about the project and its impact on the local community.

The NOvA project will construct the NuMI Off-Axis Electron Neutrino Appearance (NOvA) detector facility, a laboratory of the University of Minnesota’s School of Physics and Astronomy, near the Ash River, about 40 miles southeast of International Falls. The lab will house a 15,000-ton particle detector that will investigate the role of subatomic particles called neutrinos in the origin of the universe.

“The NOvA project will fundamentally expand our understanding of neutrinos, but it will also help strengthen scientific partnerships between the University of Minnesota and Fermilab in my district,” Congressman Foster said. “Fermilab is where much of detector equipment is being built, and the neutrino beams also originate at Fermilab. This project represents the kind of investment that simultaneously supports basic scientific research, our national labs and our economy.”

Construction of the facility, supported under a cooperative agreement for research between the U.S. Department of Energy and the University of Minnesota, is expected to generate 60 to 80 jobs. In addition, the construction will result in procurements for concrete, steel, road-building materials and mechanical and electrical equipment from U.S. firms.

“The NOvA project is an investment in our scientific future that will help us to better understand the role that neutrinos have played in the evolution of the universe,” said Dennis Kovar, DOE Associate Director of Science for High Energy Physics. “NOvA’s groundbreaking reaffirms America’s commitment to retaining its position of leadership in accelerator-based particle physics.”

The NOvA project involves about 180 scientists and engineers from 28 institutions. The collaboration will build the neutrino detector and install it in the new laboratory. When the detector is completed, physicists will explore the mysterious behavior of neutrinos by examining pulses of neutrinos sent straight through the earth from Fermilab in Illinois to the NOvA detector facility in Minnesota. The neutrinos travel the 500 miles in less than three milliseconds.

“The planning for the NOvA Facility has been years in the making, and we’re very excited that it is becoming a reality,” said University of Minnesota physics professor Marvin Marshak, a lead faculty member on the project. “This project will provide tremendous opportunities for University of Minnesota faculty and students to work with experts from around the world on important research.”

The new laboratory expands the university’s international reputation as a leader in neutrino research. The University of Minnesota currently runs the Soudan Underground Laboratory near Tower, Minn., the only laboratory of its kind in the United States.

Batavia, Ill.—The U.S. Department of Energy has named the U.S. Compact Muon Solenoid detector project as a recipient of the DOE Secretary’s Award for Achievement. DOE presents the awards to management teams that demonstrate significant results in completing projects within cost and schedule. Fermilab physicist Dan Green will accept the award on behalf of the U.S. CMS collaboration on March 31, at the 2009 Annual DOE Project Management Workshop in Alexandria, Virginia.

The U.S. CMS collaboration will share the award for the detector project with the U.S. ATLAS collaboration. The projects provide a unique opportunity for U.S. scientists to participate in the largest collaborative effort ever attempted in the physical sciences. Fermi National Accelerator Laboratory serves as the host laboratory for the U.S. CMS project. Brookhaven National Laboratory hosts the U.S. ATLAS project. Scientists from U.S. universities and national laboratories contributed key components and expertise to the state-of-the-art detectors built for the Large Hadron Collider at CERN, the European laboratory for particle physics, in Geneva, Switzerland.

“This award is a tribute to the entire U.S. CMS collaboration,” said Green, who currently serves as the CMS Collaboration board chair. “It recognizes the team efforts of more than 700 scientists who built one-third of the detector on time and on budget.

CMS has approximately 2,300 international collaborators. Supported by the DOE Office of Science and the National Science Foundation, the U.S. CMS collaboration consists of roughly 420 Ph.D. physicists, over 100 graduate students and nearly 200 engineers, technicians, and computer scientists from 48 U.S. universities and Fermilab. The U.S. is the largest single national group in the experiment.

“I congratulate Fermilab and Dan Green on effectively managing the U.S. CMS detector project,” said Pepin Carolan, who served as DOE Federal Project Director for U.S. CMS and U.S. ATLAS. “Both U.S. ATLAS and U.S. CMS play a critical role in training future generations of scientists to maintain U.S. leadership in science, technology and innovation.”

Funds are part of $1.2 billion from Recovery Act to be disbursed by Department of Energy’s Office of Science

Batavia, Ill.—In the first installment of funding from the U.S. Department of Energy’s Office of Science under President Obama’s American Recovery and Reinvestment Act, DOE’s Fermi National Accelerator Laboratory will receive $34.9 million.

The funds are part of $1.2 billion announced by Secretary of Energy Steven Chu today from funding allocated under the Recovery Act to DOE’s Office of Science. The funds will support an array of Office of Science-sponsored construction, laboratory infrastructure, and research projects across the nation. The Secretary made the announcement during a visit to Brookhaven National Laboratory, in Upton, NY.

“Leadership in science remains vital to America’s economic prosperity, energy security, and global competitiveness,” said Secretary Chu. “These projects not only provide critically needed short-term economic relief but also represent a strategic investment in our nation’s future. They will create thousands of jobs and breathe new life into many local economies, while helping to accelerate new technology development, renew our scientific and engineering workforce, and modernize our nation’s scientific infrastructure.”

The Fermilab allocation is part of $1.2 billion that Secretary Chu announced is being disbursed now in the first installment of a total of $1.6 billion allocated to the DOE Office of Science by Congress under the Recovery Act legislation. Officials are working on details remaining to enable approval and release of the balance of $371 million.

Fermilab will invest the funds in critical scientific infrastructure to strengthen the nation’s global scientific leadership as well as to provide immediate economic relief to local communities. The laboratory will use $25 million for construction and improvement projects that will generate engineering and construction jobs in Illinois businesses and pay for materials and services purchased from U.S. companies. The laboratory will devote the remaining $9.9 million to purchasing key high-tech components from U.S. companies for the NOvA neutrino project, allowing these firms to retain and hire workers.

In addition to the $34.9 million for Fermilab, the initial round of Office of Science funding provides $40.1 million to the University of Minnesota for construction of the Fermilab-managed NOvA neutrino experiment. The NOvA funding for Minnesota will generate an estimated 60-plus construction jobs and procurements for concrete, steel, road-building materials and mechanical and electrical equipment from U.S. firms.

“At Fermilab, we are committed to put Recovery Act funding to work in the way the nation intends: to strengthen our country’s long-term future by investment in basic science and to provide immediate economic help for our local communities and the nation by creating jobs and buying materials and services,” said Fermilab Director Pier Oddone. “We are ready to move forward today.”

This isn’t your average field trip. This month, more than 6,000 high school students participating in Hands-on Particle Physics Masterclasses will have the chance to form national or international scientific collaborations, just like real particle physicists do.

With the help of particle physicists, about 400 students from across the United States will analyze data from large particle collider experiments at CERN, the European Center for Nuclear Research. Most students will participate in this activity at universities and research institutes near their schools.

Classroom groups will discuss their findings via videoconference with other groups of students from across the country or across the globe. Physicists at Fermi National Accelerator Laboratory, including the laboratory’s deputy director, Young-Kee Kim, will help moderate videoconferences.

“This is a great opportunity to give students a deeper understanding of particle physics,” Kim said. “I hope this program will inspire them.”

This year high school students from around the world will participate in the international Hands-on Particle Physics Masterclass program, which began in Europe in 2005 and has expanded into the United States, South Africa and Brazil. Scientists at more than 100 universities and laboratories in 23 countries, including 22 institutions in the United States, will host students.

Students in the United States will participate through QuarkNet, a national program that unites high school students, physics teachers and particle physicists.

The opportunity to experience state-of-the-art research in an authentic environment will give students insight into the international organization of modern research. At the same time, they will learn about the building blocks of our universe through presentations by scientists involved in particle physics research.

“The Masterclass gives students the opportunity to understand the way physicists do high-energy physics,” said Jeff Rylander, instructional supervisor for the science department at Glenbrook South High School in Glenbrook, Ill. Rylander brought eight of his students to Argonne National Laboratory for a Masterclass last year and worked with a particle physicist from Fermilab.

“They appreciated looking at real data and interacting with a real physicist,” he said.

Summer Blot, now a physics student at the University of Chicago, attended the Masterclass last year with her QuarkNet group at Mills E. Goodwin High School in Richmond, Va. “It was neat that after only about an hour or two of learning how to do it, we were able to try analyzing data,” she said. “It made me realize that this is really what I want to do.”

Most students have to wait until graduate school to do that kind of data analysis, Blot said. “The fact that I have experience with it starting my first year is amazing to a lot of people. It gave me an advantage.”

This year’s lectures will discuss the Large Hadron Collider, the particle accelerator about 17 miles in circumference at the border of Switzerland and France. Students will analyze visual displays of real data collected at LEP, the previous large particle accelerator at CERN, and simulated data produced by the ATLAS experiment at the Large Hadron Collider.

The Hands-on Particle Physics student research days take place under the central coordination of Physics Professor Michael Kobel, Technical University of Dresden, in close cooperation with the European Particle Physics Outreach Group and with the support of the Helmholtz Alliance “Physics at the Terascale,” and the German Federal Ministry of Education and Research BMBF.

QuarkNet is funded by the National Science Foundation and the U.S. Department of Energy.

Batavia, Ill.—Scientists of the CDF experiment at the Department of Energy’s Fermi National Accelerator Laboratory announced yesterday (March 17) that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. The CDF physicists have called the particle Y(4140), reflecting its measured mass of 4140 megaelectron volts. Physicists did not predict its existence because Y(4140) appears to flout nature’s known rules for fitting quarks and antiquarks together.

“It must be trying to tell us something,” said CDF cospokesperson Jacobo Konigsberg of the University of Florida. “So far, we’re not sure what that is, but rest assured we’ll keep on listening.”

Matter as we know it comprises building blocks called quarks. Quarks fit together in various well-established ways to build other particles: mesons, made of a quark-antiquark pair, and baryons, made of three quarks. So far, it’s not clear exactly what Y(4140) is made of.

The Y(4140) particle decays into a pair of other particles, the J/psi and the phi, suggesting to physicists that it might be a composition of charm and anticharm quarks. However, the characteristics of this decay do not fit the conventional expectations for such a make-up. Other possible interpretations beyond a simple quark-antiquark structure are hybrid particles that also contain gluons, or even four-quark combinations.

The CDF scientists observed Y(4140) particles in the decay of a much more commonly produced particle containing a bottom quark, the B + meson. Sifting through trillions of proton-antiproton collisions from Fermilab’s Tevatron, CDF scientists identified a small sampling of B+ mesons that decayed in an unexpected pattern. Further analysis showed that the B+ mesons were decaying into Y(4140).

The Y(4140) particle is the newest member of a family of particles of similar unusual characteristics observed in the last several years by experimenters at Fermilab’s Tevatron as well as at KEK laboratory in Japan and at DOE’s SLAC National Accelerator Laboratory in California.

“We congratulate CDF on the first evidence for a new unexpected Y state that decays to J/psi and phi,” said Japanese physicist Masanori Yamauchi, a cospokesperson of KEK’s Belle experiment. “This state may be related to the Y(3940) state discovered by Belle and might be another example of an exotic hadron containing charm quarks. We will try to confirm this state in our own Belle data.”

Theoretical physicists are trying to decode the true nature of these exotic combinations of quarks that fall outside our current understanding of mesons and baryons. Meanwhile experimentalists happily continue to search for more such particles.

“We’re building upon our knowledge piece by piece,” said CDF cospokesperson Rob Roser of Fermilab, “and with enough pieces, we’ll understand how this puzzle fits together.”

The Y(4140) observation is the subject of an article submitted by CDF to Physical Review Letters this week. Besides announcing Y(4140), the CDF experiment collaboration is presenting more than 40 new results at the Moriond Conference on Quantum Chromodynamics in Europe this week, including the discovery of electroweak top-quark production and a new limit on the Higgs boson, in concert with experimenters from Fermilab’s DZero collaboration. Both experiments are actively pursuing a very broad program of physics, including ever-more-precise measurements of the top and bottom quarks, W and Z bosons and searches for additional new particles and forces.

“Thanks to the remarkable performance of the Tevatron, we expect to greatly increase our data sample in the next couple of years, said Konigsberg. “We’ll study better what we’ve found and hopefully make more discoveries. It’s a very exciting time here at Fermilab.”
