LHC

New accelerator magnets are undergoing a rigorous training program to prepare them for the extreme conditions inside the upgraded Large Hadron Collider.

Scientists from Fermilab and other institutions hoping to find new, long-lived particles at the Large Hadron Collider recently realized, with CMS, they may already have the detector to do it.

The ATLAS experiment at CERN sees possible evidence of quark-gluon plasma production during collisions between photons and heavy nuclei inside the Large Hadron Collider.

Scientists discovered a new particle by comparing data recorded at the Large Hadron Collider and the Tevatron.

From IRIS-HEP, April 10, 2021: Allison Hall, Fermilab LHC Physics Center researcher, is quoted in this story on the hardware upgrade to CERN’s Large LHC that will significantly boost the proton beams’ intensity.

What does it take to envision and build a seemingly impossible particle accelerator? The results of these discussions will shape the next 100 years of particle physics research.

U.S. CMS physicists from Fermilab and associated universities collaborating under the umbrella of the LPC make up a team that is the first to perform a new kind of search for “stealthy” supersymmetry that does not result in an obvious signature of large energy imbalance. Instead, the LPC team is looking for collisions that result in an unusually large number of particles in the detector. CMS recently published a briefing explaining their analysis.

From CERN, March 16, 2021: The collaboration of TOTEM researchers at CERN and DØ researchers at Fermilab have discovered the oddereon – an elusive three-gluon state predicted almost 50 years ago.

From the CERN Courier, March 9, 2021: The discovery of an odderon, predicted to exist almost 50 years ago, was the result of a collaboration between CERN and Fermilab using data from the Large Hadron Collider as well as Fermilab’s DZero experiment. The results were presented at a CERN physics talk and are reported in a joint publication on the observations that were made in December 2020.

Higgs-boson pairs could help scientists understand the stability of our universe. The trick is finding them.
