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 taking 40…

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 EPS Emmy Noether Distinction for Women in Physics 2018 has been attributed to a CMS member, Dr. Chiara Mariotti "for her outstanding contributions to the discovery and characterisation of the Higgs boson, for her leading role as founder and…

A successful four years of CMS detector operation came to an end last week and now we are beginning a new chapter. The next two-years of Long Shutdown (LS2) will mark an important transition for CMS. Against a background of the intensive 5-yearly…

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…

The American Association for the Advancement of Science (AAAS) and publisher of the journal Science, has elected two CMS Collaborators, Joel Butler and Scott Thomas, as 2018 AAAS fellows. This lifetime honor comes with an expectation that recipients…

New paper charts the progress of CMS-led education initiative to empower primary school teachers towards modern physics, scientific discovery and innovation A new, open access paper, published inPhysics Education, presents the development,…

As well as making data from particle physics research public, the CMS experiment has developed additional tools in github to be used in schools It's exciting to use actual coding with real data from scientific experiments. I wish there was more of…

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…

On 1 September 2018, a new spokesperson and two deputies took over at the helm of the CMS experiment for a period of two years. The new team will lead the CMS Experiment through an important period that will include analysis of the CMS 2018 data and…
