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. It’s been twelve intense months for the growing CMS collaboration that counts 53 member countries.…

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…

The CMS electromagnetic calorimeter (ECAL) measures the energy of electrons and photons produced in the LHC collisions with extreme precision. It includes, as main active element, 75848 scintillating crystals made of lead tungstate, a material that…

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 conference organizers, the University of Adelaide, welcomed over 500…

The CMS detector is going through multiple maintenance works during the LHC Long Shutdown 2 (LS2), the first year of which is approaching its end. The beginning of 2019 saw the CMS Tracker Pixel detector extraction that is now stored in a clean room…

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. In heavy-ion physics, the properties of the quark-gluon plasma, a…

With the connection of the final cable on October 4, CMS completed the installation of new on-detector electronics for the Hadron Calorimeter (HCAL) barrel detector. Following a series of upgrades to the electronics of  various HCAL…

The CMS member Wesley Smith received the 2020 W.K.H. Panofsky Prize Prize has been a top award of the American Physical Society (APS) that aims to recognize and encourage “outstanding achievements in experimental particle physics”. On October 22nd,…

A new result by the CMS Collaboration narrows down the mass of the Higgs boson to a precision of 0.1%. After reporting the observation of the Higgs boson at the CERN LHC in 2012, scientists the ATLAS and CMS Collaborations have been busy…

On July 25th, 2019, the very first GEM superchambers were installed into the CMS YE- endcap as part of the newest CMS muon subsystem, GE1/1. And while this was a fantastic accomplishment worth celebrating, it was only the beginning of the story.…

The CMS Young Researchers Prize dates back to 2012, when seven scientists from the CMS and ATLAS collaborations, as well as from the LHC project, were recognised by the Fundamental Physics Prize Foundation for their leadership role in the discovery…

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. HGCAL is one of the most ambitious detector projects undertaken, due to the…
