... where L, R represent respectively the left- and right-handed components of quarks and leptons. This procedure easily accommodates the electron mass, as well as the masses of the other observed leptons, the muon and the tau particles. It also accommodates the so-called the current algebra masses of t ...

... Particles and Antiparticles The positron is the same as the electron, except for having the opposite charge (and lepton number). Every type of particle has its own antiparticle, with the same mass and most with the opposite quantum number. A few particles, such as the photon and the π0, are their o ...
