Here we look at what leptons are, how they fit in the Standard Model of particle physics, and their importance in atoms and particle decay.

Meet the heaviest of all the leptons, the Tauon (also known as the Tau Lepton or Tau Particle). The Tau lepton has a mass of 1777 MeV/c^2, to put this lepton into perspective, it is several ...

A particle detector flying above Antarctica has recently caused a stir in the particle physics world after it detected highly ...

The six quarks, charged leptons and neutrinos, gluons, photon, gauge bosons and Higgs boson are all that it predicts, and each particle has been not only discovered, but their properties have been ...

The lepton family also includes a kind of “superlight” particle, called a “neutrino,” that comes in three flavors associated with the other non-quark leptons: tau neutrino, muon neutrino ...

B reaking the rules is exciting, especially if they have held for a long time. This is true not just in life but also in particle physics. Here the rule I'm thinking of is called “lepton flavor ...

Dark matter, although not visible, is believed to make up most of the total mass of the universe. One theory suggests that ...

But if the virtual particle were something more exotic that interacts with each lepton differently, depending on its mass, then more taus could be created at the end because taus are the heaviest ...

Among these deviations are the multi-lepton anomalies. "From the multi-lepton anomalies one can predict the existence of a new Higgs-like boson, somewhat heavier than the one discovered in 2012.

In the strange world of particle physics, the various flavors of quarks and leptons are differentiated by their individual properties, including mass, charge and spin. Sign up for the Live Science ...

Under the Standard Model of particle physics it's classified as a "lepton." Other leptons include electrons, the negatively charged particles that make up atoms, with protons and neutrons.
