Since the discoveries of the third generation of quarks and leptons starting in the 1970s, physicists have asked the natural question "Can there be more generations?".  One of the first key results from the Large Electron Positron collider LEP...

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...

The High-Luminosity LHC is a major upgrade of the Large Hadron Collider that is expected to increase the luminosity by a factor of 10 beyond the design luminosity of the current LHC. This means, the data produced per year will be equal to the amount...

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,...
