Over the past century, physicists have developed a theory governing the fundamental interactions of elementary particles, known as the Standard Model of Particle Physics. Thus far, it has stood up to many experimental tests with an extraordinary...

The Standard Model of particle physics asserts that the Higgs boson generates the mass of all fundamental particles. In 2012 a new particle was discovered at the CERN LHC that behaves closely like the Higgs particle predicted by the Standard Model...

After the discovery of the Higgs boson, CMS observed its interaction with some standard model particles like the bottom and top quark, the tau lepton, and the W and Z boson.  Measuring the strength of interactions with quarks and leptons (called...

How long do fundamental particles live? In the Standard Model, we know particles can have many different lifetimes; from the top quark which decays in less than a millionth of a billionth of a billionth of a second, to stable particles like the...

In November 2018 the proton-proton running of the LHC Run 2 ended. The data collected in 2018 is the largest sample ever collected at the LHC. Just under three months after the final proton proton collisions were recorded, the CMS collaboration has...

The top quark is the heaviest particle in the standard model, and since its discovery in 1995 at the Tevatron collider at Fermilab, its study has become prominent in furthering our understanding of fundamental physics. At the Large Hadron Collider,...
