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 Collaboration probes decays of the Z boson which would defy our expectations of lepton behavior How strict are Nature's conservation laws governing the interactions among elementary particles? Physicists once assumed, based on experience…

CMS sees evidence of the Upsilon meson decaying into two tau leptons for the first time at a hadron collider Beyond our best current understanding of particle physics, encapsulated in the standard model, various theoretical models predict the…

The CMS experiment sets limits for BSM particles down to tens-of-MeV aided by machine learning techniques. Axion-like particles (ALPs) are hypothetical light-weight neutral bosons that could solve deep mysteries in physics, from the strong CP…
