CERN Accelerating science

2019 is approaching its end with it the first year of the LHC Long Shutdown 2 (LS2),a break that focuses on the upgrade and maintenance of the LHC.

Early one morning, residents of the Pathum Wan District of Bangkok were greeted to the rare spectacle of dozens of physicists in formal attire walking the streets of Bangkok on their way to meet Her Royal Highness Princess Maha Chakri Sirindhorn of Thailand.

The CMS electromagnetic calorimeter (ECAL) measures the energy of electrons and photons produced in the LHC collisions with extreme precision.

The 2019 edition of the International Conference on Computing in High Energy and Nuclear Physics (CHEP, chep2019.org) was held on 4–8 November in Adelaide (South Australia).

The CMS collaboration presented over ten brand-new results in the latest installment of the Quark Matter conference, one of the largest conferences in the field of heavy-ion physics.

The high-granularity calorimeter (HGCAL) is a major upgrade of CMS, and is necessary to maintain excellent calorimetric performance in the endcaps during HL-LHC operations.

Congratulations to five CMS scientists, Tulika Bose, Yuri Gershtein, Andrei Gritsan, George Wei-Shu Hou and Markus Klute, who were elected as American Physical Society (APS) Fellows in 2019 for their excepti

The CMS Gas Electron Multiplier (GEM) subsystem will form an extra layer of detectors, along with the Cathode Strip Chambers (CSC) layers, closest to the beam.

Every year the CMS Thesis Award Committee recognizes and rewards excellence in the CMS PhD student research.

The CMS collaboration at CERN is happy to announce the release of its fourth batch of open data to the public.
