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 Higgs boson is deeply connected to the mechanism that generates the masses of elementary particles. In the Standard Model (SM), which describes the properties of all elementary particles and the interactions among them, the Higgs boson…

  CMS scientists discover some of the rarest collisions that the LHC can produce – such as the scattering of light by light – and learn more about the quantum nature of electromagnetism, search for new particles, and much more. In everyday life…

  Detailed study of collisions producing top quarks reveals discrepancy with respect to theoretical predictions. The CMS collaboration has preliminarily reported an unexpected effect in interactions involving top quark pairs. These results…
