Editor’s note: The following press release was issued on Dec. 8, 2023 by the American Physical Society announcing the 2023 Particle Physics Project Prioritization Panel report.
From Fermilab Director, Lia Merminga:
“Fermilab strongly and enthusiastically supports the P5 report in its entirety. The 2023 P5 report provides an ambitious, bold and balanced vision and roadmap for U.S. high-energy physics. It strongly endorses the ongoing physics program, and prioritizes the timely completion and scientific operations of ongoing construction projects; reaffirms the science of DUNE and recommends early implementation of the definitive long-baseline neutrino oscillation experiment; encourages us to collaborate with our international partners towards an offshore Higgs factory; and supports the HEP community’s aspirations to host a muon collider at Fermilab.
“Thank you to the High Energy Physics Advisory Panel and the Particle Physics Project Prioritization Panel members for all of their hard work and time in creating this document that will guide us for the next decade and ensure continued U.S. leadership in particle physics.”
The High Energy Physics Advisory Panel (HEPAP) to the High Energy Physics program of the Office of Science of the U.S. Department of Energy and the National Science Foundation’s Division of Physics has released a new Particle Physics Project Prioritization Panel (P5) report, which outlines particle physicists’ recommendations for research priorities in a field whose projects — such as building new accelerator facilities — can take years or decades, contributions from thousands of scientists, and billions of dollars.
The 2023 P5 report represents the major activity in the field of particle physics that delivers recommendations to U.S. funding agencies. This year’s report builds on the output of the 2021 Snowmass planning exercise — a process organized by the American Physical Society (APS)’s Division of Particles and Fields that convened particle physicists and cosmologists from around the world to outline research priorities. This membership division constitutes the only independent body in the United States that represents particle physics as a whole.
“The P5 report will lay the foundation for a very bright future in the field,” said R. Sekhar Chivukula, 2023 chair of the APS Division of Particles and Fields and a Distinguished Professor of Physics at the University of California, San Diego. “There are extraordinarily important scientific questions remaining in particle physics, which the U.S. particle physics community has both the capability and opportunity to help address, within our own facilities and as a member of the global high energy physics community.”
The report includes a range of budget-conscious recommendations for federal investments in research programs, the U.S. technical workforce, and the technology and infrastructure needed to realize the next generation of transformative discoveries related to fundamental physics and the origin of the universe. For example, the report recommends continued support for the Deep Underground Neutrino Experiment (DUNE), based out of Fermilab in Illinois, for CMB-S4, a network of ground-based telescopes designed to observe the cosmic microwave background, and for the planned expansion of the South Pole’s neutrino observatory, an international collaboration known as IceCube-Gen2, in a facility operated by the University of Wisconsin–Madison.
“In the P5 exercise, it’s really important that we take this broad look at where the field of particle physics is headed, to deliver a report that amounts to a strategic plan for the U.S. community with a 10-year budgetary timeline and a 20-year context. The panel thought about where the next big discoveries might lie and how we could maximize impact within budget, to support future discoveries and the next generation of researchers and technical workers who will be needed to achieve them,” said Karsten Heeger, P5 panel deputy chair and Eugene Higgins Professor and chair of physics at Yale University.
New knowledge, and new technologies, set the stage for the most recent Snowmass and P5 convenings. “The Higgs boson had just been discovered before the previous P5 process, and now our continued study of the particle has greatly informed what we think may lie beyond the standard model of particle physics,” said Hitoshi Murayama, P5 panel chair and the MacAdams Professor of physics at the University of California, Berkeley. “Our thinking about what dark matter might be has also changed, forcing the community to look elsewhere — to the cosmos. And in 2015, the discovery of gravitational waves was reported. Accelerator technology is changing too, which has shifted the discussion to the technology R&D needed to build the next-generation particle collider.”
The United States participates in several major international scientific collaborations in high energy physics and cosmology, including the European Council for Nuclear Research (CERN), which operates the Large Hadron Collider, where the Higgs boson was discovered in 2012. The P5 report recommends that the United States support a significant in-kind contribution to a new international facility, the ‘Higgs factory,’ to further our understanding of the Higgs boson. It also recommends that the United States study the possibility of hosting the next most-advanced particle collider facility, to reinforce the country’s leading role in international high energy physics for decades to come.

Ten international funding agencies will contribute to the construction of the gigantic particle detectors a mile underground for the Fermilab-hosted Deep Underground Neutrino Experiment.
The Deep Underground Neutrino Experiment — also known as DUNE — is an international mega science experiment that will use enormous particle detectors to study the behavior of neutrinos, which might indicate why we live in a matter-dominated universe.
The DUNE collaboration, representing scientists from dozens of countries around the world, will contribute to the construction of detectors at two sites in the United States: one at the U.S. Department of Energy’s Fermi National Accelerator Laboratory, the host lab for DUNE, 40 miles west of Chicago, and the other at the Sanford Underground Research Laboratory (SURF) in Lead, South Dakota.
On Nov. 17, representatives of funding agencies from five countries signed a memorandum of understanding, affirming their commitment to contribute to the construction of components for DUNE. Director Lia Merminga signed on behalf of Fermilab.

“DUNE will help answer some of the biggest questions in the universe and has the potential to transform the field of neutrino physics. We are proud to host DUNE in the U.S. with major contributions from the project’s international partners who offer their unique expertise,” said Regina Rameika, DOE associate director for the Office of High Energy Physics. “Having the commitment from our international partners to contribute these vital components is an essential aspect of DUNE.”
With their signatures, University of Campinas (Unicamp), Brazil, Institut National de Physique Nucléaire et de Physique des Particules (IN2P3), France, Istituto Nazionale Di Fisica Nucleare (INFN), Italy, University of Bern, Switzerland and the Science and Technology Facilities Council/United Kingdom Research and Innovation (STFC/UKRI), United Kingdom, committed to contributing hardware to the two DUNE Far Detectors in South Dakota.
The Canadian Foundation for Innovation John R. Evans Leaders Fund and the Ontario Research Fund in Canada in addition to CERN in Switzerland also signed the memorandum of understanding remotely and will contribute to the DUNE Near Detector in Batavia, Illinois.
Signatures from agencies in the Czech Republic and Spain have been coordinated and will be finalized in the future.
In the memorandum of understanding for Far Detector 1, the United Kingdom and CERN agreed to contribute to anode plane assemblies; Brazil, the Czech Republic, Italy and Spain will contribute to the photon detection system; CERN will contribute to the high-voltage system; Canada, CERN and the U.K. will contribute to the data acquisition system; and Spain will contribute to the calibration and cryogenics instrumentation.
In the memorandum of understanding for Far Detector 2, CERN and France agreed to contribute to top drift electronics; Brazil, the Czech Republic, France, Italy and Spain will contribute to the photon detection system; France and CERN will contribute to the high-voltage system; Canada, CERN and the U.K. will contribute to the data acquisition system; Spain will contribute to the calibration and cryogenics instrumentation; and CERN and France will contribute to the charge readout planes.
Scientists and engineers from more than 35 countries are partnering with Fermilab to design, build and analyze data from DUNE, which will be installed in the new Long-Baseline Neutrino Facility. Construction of LBNF has begun, and the excavation of the large caverns in Lead, South Dakota for the DUNE Far Detectors is more than 85% complete.
The DUNE collaboration comprises more than 1,400 scientists and engineers from over 200 research institutions. Notably, CERN’s commitment to LBNF and DUNE represents its first investment in infrastructure for a physics experiment outside of Europe. Several countries — France, India, Italy, Poland and the United Kingdom — also are making significant contributions to the Proton Improvement Plan II project, which includes the construction of the 215-meter-long superconducting particle accelerator at Fermilab that will power DUNE.
DUNE will be the world’s most comprehensive experiment to study neutrinos: tiny, lightweight particles that permeate the universe but rarely interact with anything. DUNE will seek to determine whether neutrinos could be the reason the universe is made of matter; look for neutrinos emitted from exploding stars to learn more about the formation of neutron stars and black holes; and watch for a rare subatomic phenomenon that could elucidate the unification of nature’s forces.
To pursue these science goals, DUNE will study neutrino oscillation, a phenomenon in which a neutrino’s property, called flavor, changes as it travels. DUNE will probe this oscillation by shooting a beam of neutrinos 1,300 kilometers straight through the earth, from Fermilab’s accelerator complex in Illinois, through the Near Detector to the Far Detectors located a mile underground at SURF in South Dakota.
The science of DUNE is a global endeavor, and the partnership with funding agencies, scientists and engineers from around the world makes it the first truly international mega science experiment to be hosted on U.S. soil. Additionally, hundreds of students from all corners of the earth will start their careers in science, engineering and computing on this project.

Although firefighters in the Chicagoland region train extensively to fight fires in buildings, they don’t often train for fires erupting in natural areas, especially with live fires.
In early November, the U.S. Department of Energy’s Fermi National Accelerator Laboratory hosted the three-day training on combatting wildland fires. With more than 50 people attending this training, eight different municipalities and four conservation forestry groups from Cook, Will and DuPage counties were represented. Run by the Illinois Fire Service Institute, the Statutory Fire Academy for Illinois at the University of Illinois Urbana-Champaign trains more than 60,000 first responders across the state.

“We are thankful to Fermilab for opening their doors to our firefighters,” said Tom Richter, the wildland/prescribed fire program manager at IFSI. “Training is an essential part of being a firefighter, and allowing structural firefighters to train in wildland fire settings creates a safer Illinois.”
Wildlands are uncultivated sections of land set aside as a protected wilderness area, and fires in wildland settings can be caused by lightning or by people. Structural firefighters are trained to extinguish fires in buildings where they often have access to fire hydrants.
“In wildlands, we’re out in the open; there are no fire hydrants. So, in essence, the fire engines become the fire hydrants,” said Steve Hernandez, the fire chief for Fermilab’s Fire Department.
“Firefighters also fight wildland fires with fire by burning large areas to take away the fuel,” Hernandez said, “or we use tools to clear the lands and create a break between the area that is burning and the area that has not been affected.”
During the course, the firefighters learned about the basics of wildland fires and fire safety. The training covered the types of topography that can influence wildfires and how different plants can fuel the fires. They learned how weather and especially unpredictable winds can pose challenges for wildland firefighting. As live fires were used in Fermilab’s wildland areas for this training, preparation was essential and involved careful coordination with Fermilab’s ecology team.
Fire as a useful tool for ecological maintenance
Fermilab has more than 6,000 acres of land—10 square miles—with a large section that includes restored prairie, woodlands and other ecosystems. Intentional, controlled fires known as prescribed burns are one of the most effective land management tools to help Fermilab’s natural areas thrive. Fermilab’s ecology team regularly conducts prescribed burns on site in the spring and the fall, which made the lab an ideal place to conduct the IFSI training.
“Fire is a disturbance that keeps woody plants out, like brush and trees, so repeated fires help maintain a healthy prairie,” said Wally Levernier, Fermilab’s ecologist.
Left unchecked, trees and brush create shade that can prevent prairie dependent plants from growing, which destabilizes prairie ecosystems by creating a domino effect that can negatively impact pollinators.
“One of the other advantages of prescribed burning is specifically for our invasive species management,” said Levernier. “Imagine going through a prairie that hasn’t had a prescribed burn on it in the spring and looking for little sprouts of invasive species between the layers of thatch from previous years’ growth.”
Prescribed burns create a clean slate to spot invasive species when they emerge and help provide room for native species to establish themselves.
The wildland fire training provided much needed maintenance for Fermilab’s natural areas, while also deepening ties between Fermilab’s fire department and the fire departments that serve the surrounding communities.
“Fermilab’s fire department frequently trains with our community partners,” said Hernandez. “Because of that, we can effectively coordinate our efforts to keep people safe when we do need their personnel and resources.”

The mission of U.S. Department of Energy’s Fermi National Accelerator Laboratory is to conduct experiments that push our understanding of the fundamental building blocks of matter. Part of that mission includes outreach to educate the public about the work done at the lab.
On Sunday, Oct. 22, Fermilab’s Office of Education and Public Engagement hosted its Outdoor Family Fair, which brought the public to the lab to enjoy educational activities about some of its science, as well as to get a close look at Fermilab’s diverse site. The free event saw more than double the turnout of the last Outdoor Family Fair, held in 2019.
Fermilab’s 6,800-acre campus includes restored prairies, a rich ecology and a prized herd of bison, all of which were on display during the 2023 Outdoor Family Fair. Other activities included the Northern Illinois Raptor Rehab and Education exhibiting live raptors. Attendees could participate in a lab timeline scavenger hunt to learn about Fermilab’s history and future. Mr. Freeze put on his always popular liquid-nitrogen show, and a demonstration of quantum entanglement taught guests about basics of quantum mechanics.
