The word lepton comes from the Greek λεπτός (leptós,) meaning “small”;  the electrically charged leptons (electrons, muons, and taus) have much smaller masses than their counterparts in the quark sector. For example, the tau particle is the heaviest…

The collision of high-energy protons at the LHC breaks them apart and allows us to look at its constituents. Surely there are more interesting stuff in store, compared to the usual constituents at lower energy, the up and the down type quarks.…

The Higgs boson is peculiar in many respects. Like most other elementary particles, it is unstable and lives only for an extremely short time, 1.6 x 10-22 seconds, according to the established theory of particle physics (the standard model). Pretty…
