CMS

The Compact Muon Solenoid (CMS) is a general-purpose detector at the Large Hadron Collider (LHC). It is designed to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter. Although it has the same scientific goals as the ATLAS experiment, it uses different technical solutions and a different magnet-system design.

First lead-ion collisions in the LHC at record energy

On Friday, 18 November, a test using collisions of lead ions was carried out in the LHC and provided an opportunity for the experiments to validate the new detectors and new data-processing systems ahead of next year’s lead-lead physics run.

CMS measures rare particle decay with high precision

Using LHC Run 2 data, CMS has precisely measured the rare decay of strange B-mesons to muon-antimuon pairs. While its properties agree with Standard Model predictions, it may provide clues to new discoveries in Run 3

Higgs10: When spring 2012 turned to summer

It was just a few short weeks in mid-2012, but they were so intense that it felt like years. As 4 July drew near, the ATLAS and CMS experiments could sense that they were homing in on something big.
