In November 2018 the proton-proton running of the LHC Run 2 ended. The data collected in 2018 is the largest sample ever collected at the LHC. Just under three months after the final proton proton collisions were recorded, the CMS collaboration has...

*/ The CMS detector is built from several different layers, surrounding the beam pipe in which the LHC beams collide. The subdetector that is closest to the collisions is the pixel detector. It has a functionality similar to a digital camera...

After the LHC was shut down at the end of 2018, one might think that physicists working in the large experiments can sit back and relax. On the contrary, CMS will undergo an intensive upgrade and maintenance program during the two-year long break in...

The top quark is the heaviest particle in the standard model, and since its discovery in 1995 at the Tevatron collider at Fermilab, its study has become prominent in furthering our understanding of fundamental physics. At the Large Hadron Collider,...

On Sunday 2nd December CMS recorded the last collisions to bring to a close a very successful LHC second running period (Run 2) that began in 2015. LHC has delivered to CMS 68 fb-1 of proton-proton collisions and almost 1.8 nb-1 of Pb-Pb collisions...

We are nearing the end of the year and LHC started colliding another species of particles than protons: the nuclei of heavy atoms. These so-called “heavy-ion” collisions are used to study the properties of a particle soup known as the “quark-gluon...

When the Large Hadron Collider is in operation, the cavern containing the CMS detector is an extremely inhospitable place, due to the high-energy radiation produced by the collisions. Even after a LHC fill finishes, some residual radioactivity can...
