Z bosons produced in collisions of heavy ions have been observed for the first time by the CMS experiment at CERN’s Large Hadron Collider (LHC). CMS observed 10 events containing a distinctive candidate Z boson reconstructed from a pair of electrons…

The CMS Collaboration at CERN released today a paper entitled "Observation of Long-Range Near-Side Angular Correlations in Proton-Proton Collisions" that details signs of a new phenomenon in proton interactions. A study of "high multiplicity"…

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 recent results from the Muon g-2 Collaboration have added to the growing tension between the measured and predicted values of the muon’s magnetic moment. The equivalent measurement of this property for the electron is a cornerstone of quantum…

  New in! CMS physicists search for heavy cousins of the neutrino in beauty meson decays Back in 2018, the physicists of the CMS experiment designed and recorded a B-meson-enriched data sample, the “B-Parking” data set. The B mesons (short for…
