Since late May, with the incremental re-opening of CERN’s facilities, members of the CMS GEM project have been hard at work restarting the laboratory activities in preparation for the continued efforts towards the GE1/1 chambers installation. Made…

The CMS experiment at CERN is happy to announce a new batch of open data from the Large Hadron Collider (LHC), this time encompassing all the data recorded by CMS in 2011. With this release, CMS has brought all proton-proton collision data recorded…

At the ICHEP2020 conference, held virtually in Prague this summer, the CMS collaboration presented a new, precise analysis of the data enriched in the Higgs boson decays to four leptons. Simultaneous measurement of the Higgs boson production and…

What if new particles modify the behaviour of existing particles, but by only a little bit? In a new result, CMS physicists search for new physics using a technique called Effective Field Theory to study the top quark in a "toy universe". We have…

A new result released by the CMS Collaboration presents the first evidence of the Higgs boson interacting with the muon. The standard model of particle physics describes all the known fundamental particles in the Universe. A mystery of the standard…

In 2012 the ATLAS and CMS collaborations discovered a boson with a mass of 125 GeV, i.e. approximately 125 times the mass of the proton, in proton-proton collisions at the CERN LHC. This has marked a milestone in high energy physics, as this…

Measuring the interaction between the Higgs boson and other particles is essential to understand if the particle behaves consistently with predictions. For the International Conference of High Energy Physics 2020, the CMS experiment has released…

A question researchers at the LHC are trying to answer is whether the properties of the Higgs boson are as predicted by the standard model. One way to do this is to look for extremely rare decays of the Higgs boson, as physicists in the CMS…

Eight years ago, at the largest International Conference on High Energy Physics (ICHEP), the discovery of a new particle carefully coined as Higgs boson-like was announced by the ATLAS and CMS Collaborations. They had seen an excess in data over…
