LHC

From CERN Courier, Jan. 13, 2021: The US LHC Accelerator Upgrade Project, led by Fermilab scientist Giorgio Apollinari, is now entering the production phase in the construction of magnets for the upcoming High-Luminosity LHC, an upgrade of the current Large Hadron Collider. U.S. labs are building magnets that will focus beams near the ATLAS and CMS particle detectors.

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning — but many researchers are not giving up on it yet.

From Phys.org, Dec. 7, 2020: The CMS collaboration, a worldwide group of scientists studying particle collisions at CERN’s Large Hadron Collider, has recently observed the production of three massive gauge bosons in proton-proton collisions for the first time ever. Northwestern University postdoc and Fermilab Distinguished Researcher Saptaparna Bhattacharya talks about the triboson search.

When two heavy ions collide inside a particle accelerator, they produce a near-perfect fluid through which an assortment of fundamental particles swim. For scientists to accurately simulate even a tiny drop of this hot and dense subatomic brew with a classical computer, it would take longer than the age of the universe. Scientists show how quantum computing could be a game-changer in our understanding of quantum processes.

From the CMS collaboration, Nov. 30, 2020: On Nov. 24, the CMS collaboration at CERN’s Large Hadron Collider announced the publication of the 1,000th paper in a peer-review journal, an exceptional achievement for a single experiment. Fermilab scientist Boaz Klima, CMS Publications Committee chair, is quoted.

A recent observation of an extremely rare subatomic process allows scientists to test the Standard Model’s boundaries.

Fermilab scientists have implemented a cloud-based machine learning framework to handle data from the CMS experiment at the Large Hadron Collider. Now they can begin to use graph neural networks to boost their pattern recognition abilities in the search for new particles.

Particle accelerators like the LHC require intricate beam dump systems to safely dispose of high-energy particles after each run.

Scientists on an experiment at the Large Hadron Collider see massive W particles emerging from collisions with electromagnetic fields. How can this happen?

Scientists on experiments at the LHC are redesigning their methods and building supplemental detectors to look for new particles that might be evading them.
