New vacuum chambers are being developed for the ALICE and CMS experiments

CMS has also provided open access to 100% of its research data recorded in proton–proton collisions in 2010

ATLAS and CMS have studied the Higgs boson with the largest sample of proton–proton collision data recorded so far

The CMS collaboration has searched for collision events in which the Higgs boson transforms into a photon and a hypothetical dark photon

During LS2, CMS will install 144 additional muon detector modules specially designed to detect particles produced in the very forward region

The latest experimental data provide more stringent tests of the Standard Model and of rare phenomena of the microworld

Researchers from the CMS experiment at the Large Hadron Collider are developing a new application based on one of the experiment’s particle detectors

With the LHC switched off for a two-year technical stop, CMS is undergoing significant maintenance and upgrades

The CMS collaboration at CERN has submitted its first paper based on the full LHC dataset collected in 2018 and data collected in 2016 and 2017

On 1 September 2018, a new spokesperson and two deputies took over at the helm of the CMS experiment

As well as making data from particle physics research public, the CMS experiment has developed additional tools in github to be used in schools

The main LHC collaborations present a wealth of new results at this year’s Quark Matter conference
