CMS

After a quarter of a century of searching, physicists have discovered a rare particle decay that gives them an indirect way to test models of new physics.

The new particle discovered at experiments at the Large Hadron Collider last summer is looking more like a Higgs boson than ever before, according to results announced today.

Physicists on experiments at the Large Hadron Collider announced today that they have observed a new particle. Whether the particle has the properties of the predicted Higgs boson remains to be seen.

Two experimental collaborations at the Large Hadron Collider, located at CERN laboratory near Geneva, Switzerland, announced today that they have significantly narrowed the mass region in which the Higgs boson could be hiding.

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.

An international collaboration of scientists today sent the first beam of protons zooming at nearly the speed of light around the world’s most powerful particle accelerator-the Large Hadron Collider (LHC) located at the CERN laboratory near Geneva, Switzerland

Batavia, Ill. – Early yesterday morning (Jan. 22), scientists of the U.S. CMS collaboration joined colleagues around the world to celebrate the lowering of the final piece of the Compact Muon Solenoid detector into the underground collision hall at CERN in Geneva, Switzerland. The near completion of the CMS detector marks a pivotal moment for the international experiment, in preparation for the start-up of the Large Hadron Collider this summer. CMS has approximately 2,300 international collaborators. Supported by the Department…

Scientists of the U.S. CMS collaboration today (Dec. 20) joined colleagues around the world in announcing the successful installation of the world’s largest silicon tracking detector at CERN in Geneva, Switzerland.

Scientists of the US CMS collaboration joined colleagues around the world in announcing today (February 28) that the heaviest piece of the Compact Muon Solenoid particle detector has begun the momentous journey into its experimental cavern 100 meters underground.

Scientists of the U.S. Department of Energy/Office of Science’s Fermi National Accelerator Laboratory and collaborators of the US/CMS project have joined colleagues from around the world in announcing that the world’s largest superconducting solenoid magnet has reached full field strength in tests at CERN, the European Particle Physics Laboratory.
