An international collaboration is upgrading the CMS detector at CERN to handle the increased number of collisions that the High-Luminosity Large Hadron Collider will produce.
HL-LHC
U.S. CMS scientists receive $7.6 million from the U.S. Department of Energy toward CMS detector upgrades.
A full-size, US-produced HL-LHC quadrupole magnet based on niobium–tin technology has passed a critical endurance test, another step toward confirming the technology’s viability inside accelerators.
A new search for Higgs boson pairs with the CMS experiment has pushed us closer than ever to a measurement of the Higgs boson self-coupling.
A CERN photographer and videographer writes about his experiences documenting the ongoing upgrade that will turn the Large Hadron Collider into the High-Luminosity LHC.
From CERN, March 24, 2021: A memorandum of understanding (MoU) between CERN and Fermilab, signed on 23 March, details Fermilab’s contributions to the High-Luminosity LHC project.
Higgs-boson pairs could help scientists understand the stability of our universe. The trick is finding them.
For researchers interested in unlocking the mysteries of the universe, having access to the most powerful high-energy accelerator on the planet, a world-class detector, and young, fresh, and enthusiastic minds are a winning combination – and the Fermilab CMS Department has all three.
The U.S. Department of Energy has given the U.S. High-Luminosity Large Hadron Collider Accelerator Upgrade Project approval to move full-speed-ahead in building and delivering components for the HL-LHC, specifically, cutting-edge magnets and accelerator cavities that will enable more rapid-fire collisions at the collider. The collider upgrades will allow physicists to study particles such as the Higgs boson in greater detail and reveal rare new physics phenomena. The U.S. collaborators on the project may now move into production mode.
Later this decade, the Large Hadron Collider will be upgraded to the High-Luminosity LHC. What does “luminosity” mean in particle physics, and why measure it instead of collisions?
