For the past four months the LHC has been ramping-up the intensity of the beams, creating billions of 7 TeV proton-proton collisions. This has enabled CMS to study a variety of known physics from the Standard Model, including the "re-discovery" of…

The first 7 TeV (3.5 TeV + 3.5 TeV) collisions took place on 30th March 2010, starting around 1pm local (Geneva) time and lasting for about 3.5 hours. Read the CERN Press Release here. The CMS detector and its collaborators are all eagerly awaiting…

  The CMS experiment achieves the most precise determination of the strength of the strong nuclear force using the rates of production of jets at several centre-of-mass energies. The strengths of the fundamental interactions in Nature drive the…

  For the first time, the CMS experiment has employed physics-informed machine learning to observe whether the laws of physics still hold true when top quarks and Z bosons are replaced with their antiparticles and space is reflected. We know…

  The CMS experiment presents the first-ever search for a Higgs boson decaying to charm quarks when the Higgs boson is produced along with two top quarks. The Higgs boson plays a central role in our understanding of the fundamental forces of…

  By studying events with only a single energetic photon, the CMS experiment places some of the most stringent constraints to date on dark matter models and theories predicting extra dimensions of space. One way to explore physics beyond the…

CMS presents the most precise measurement of WWZ production to date by combining Run 2 data with more recent Run 3 data. The electroweak interaction provides a unified description of the electromagnetic and weak forces, but this symmetry is broken…

An excess in data hints at the existence of a top quark-antiquark quasi-bound state, called “toponium”. The CMS collaboration has reported an excess in interactions involving top quark pairs. The results are consistent with a pair of top quark and…
