During LHC Run 3, researchers at the experiment have deployed an innovative machine learning technique that will improve the data quality of one of the detector’s most crucial components

For the next 17 days, every minute counts when it comes to taking lead–lead collision data

Fabiola Gianotti, CERN Director-General, was spokesperson of the ATLAS experiment at the Large Hadron Collider from 2009 to 2013 and responsible for announcing the discovery of the Higgs boson, alongside the CMS spokesperson

The eagerly awaited result is the most precise measurement of the W mass made at the LHC so far, and is in line with the prediction from the Standard Model of particle physics

The results open up a new perspective on the complex world of quantum physics

CERN’s accelerators show very good availability rates: beams are in place

Re-analysing LHC Run 2 data with cutting-edge analysis techniques allowed CMS physicists to address an old discrepancy

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

The CMS collaboration has searched for new physics in a rare decay of a known particle, using an approach that can be likened to shaking a box containing a birthday present to find a clue about what’s inside

Using a cutting-edge AI algorithm, the CMS collaboration has obtained the first evidence of CP violation in the decay of the strange beauty meson into a pair of muons and a pair of electrically charged kaons

The collaboration has also made publicly available the software that it developed to search for the unique particle

How an evacuation of the CMS experimental cavern has provided invaluable human behaviour data to improve emergency preparedness for complex underground facilities
