While experimental results at the LHC continue to show good agreement with the standard model (SM), which is currently the best theory of fundamental particle interactions, the CMS physicists continue to turn up the heat on the SM. In fact, it is…

The heaviest known particle, the top quark, is one of our main gateways to search for new phenomena that are not addressed by our existing knowledge, the standard model of particle physics (SM), either through precision measurements of the top…

The CMS collaboration welcomes its ninth management team: the new spokesperson, Patricia McBride, and the two deputies, Wolfgang Adam and Lucia Silvestris, will represent the Collaboration for the next two years. With more than 5000 scientists,…

While the CMS detector takes data 24 /7, physicists take turns in the control room every 8 hours, ensuring continuity of operations and keeping the detector running continuously. Experts located around the world are present at all times to respond…

Have you heard of vector-like quarks? They are hypothetical particles which would provide an explanation to the value of the Higgs boson mass, which is still a mystery. Vector-like quarks are predicted by a variety of theories beyond the Standard…

Rare events, such as a total solar eclipse or a supernova explosion, are fascinating and stimulate our imagination. In addition, such events may lead to discoveries expanding our ​​knowledge horizon. At the Large Hadron Collider (LHC), studies of…

CMS has developed a new method to measure the properties of the top quark with high precision. It relies on an innovative way to cluster particles into jets.  The top quark is the most massive elementary particle we have discovered so far. Due…

The processes that are mostly studied at the LHC are caused by energetic collisions where the protons break up into their constituents, the quarks and gluons, which recombine to form composite hadrons. However, many proton-proton interactions result…

The long-awaited LHC Run 3 has started! Yesterday, 5th of July 2022, the Large Hadron Collider (LHC) at CERN delivered proton-proton collisions at the energy of 13.6 trillion electron volts (TeV) for the first time, setting a new world record. The…

Exactly ten years ago, on the 4th of July 2012, the ATLAS and CMS experiments announced the discovery of a new particle compatible with the long-sought Higgs boson.   This discovery takes us back to the events occurring in our early…

Building the huge and complex CMS detector was a big engineering challenge but the contribution of industrial companies all across the globe made it possible. Their contributions are not only limited to the construction phase of the detector but are…

As every year, we are happy to congratulate the CMS award winners! CMS Collaboration is proud to successfully advance knowledge, scientific research and technology for years but, no doubt, all this would not have been possible without the…
