CMS has just finished wrapping the barrel with a new layer which is not a new detector but a brand new protection system aimed to keep the outer barrel muon chambers shielded from background radiation present in the experimental cavern during…

When visitors at CMS enter the cavern and see the detector in all its beauty, they often ask how it has been possible to fit everything together and to make it work as a singular instrument. When the detector is in an open configuration, typically…

A new result by the CMS collaboration accepted by the journal Physical Review Letters demonstrates for the first time that top quarks are produced in nucleus-nucleus collisions. At the same time, this also demonstrates the capability of the CMS…

It is the dream of all particle physicists to find a new particle or to reveal a new fundamental force. In 2012 this dream came true when the big CERN experiments ATLAS and CMS discovered the Higgs particle, predicted by theorists decades ago. Other…

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…
