The CMS Collaboration has recently reported a new study of ZZ+jets production, a process described by the Standard Model of particle physics. The goal of such measurements is to compare the observed results with the theoretical predictions; any…

  Data taking is restarting in CMS for the continuation of Run 3 - and with it the enormous responsibility of keeping the data safe and making sure it is usable in order to conduct the physics analyses. Last April 2023, the Large Hadron…

Congratulations to Angira Rastogi, Willem Verbeke, and David Walter who won the 2022 CMS Ph.D. Thesis Award! The CMS Collaboration recognizes annually the outstanding achievements of young scientists through this award and highlights the exceptional…

The time for the 2022 CMS awards has come and we are glad to present the winners! Every year the CMS Award committee is honoring some of the CMS Collaboration’s members for their outstanding work and dedication to the CMS sub-detectors. "We are very…

  Everything started in early September 2022 while, during the ECAL Operations meeting that we hold every Wednesday morning, our veteran electronics expert, Evgueni, reported that the voltage in a control card was unstable. He prophetically…

  CMS presented a series of new results at the annual LHCP conference, which took place in Belgrade, Serbia.  The LHCP conference provides a detailed review of the latest experimental and…

The discovery of the Higgs boson in 2012 marked a significant milestone in particle physics. Since then, researchers at the ATLAS and CMS Collaborations have been diligently investigating its properties and probing for rare production and decay…

The standard model (SM) of particle physics is by far the most successful theory describing the experimental observations of particle interactions. Most of the SM interactions preserve the “flavor” of the elementary particles, with the exception of…

The top quark is now a full grown adult - it’s been almost 30 years since its discovery at Fermilab! - and being the heaviest brick of the Standard Model it plays a big part in the Universe. It is a bit like a celebrity in the world of particle…

In the thrilling world of particle physics, our mission at the Large Hadron Collider (LHC) is to explore the mysteries of the universe by conducting experiments and pushing the boundaries of the Standard Model (SM). The SM is a wonderful theoretical…

Bosons are elementary particles in the field of particle physics, distinguished by having a spin quantum number with an integer value. They play a crucial role in mediating the fundamental forces of nature, including the electromagnetic force and…

The standard model (SM) of particle physics, is the most successful theory describing the behaviour of elementary particles and their interactions. However, the SM has a few serious shortcomings, such as the Higgs boson mass problem. The mass of the…
