English

Etymology

From anti- +‎ lepton.

Noun

antilepton (plural antileptons)

  1. (particle physics) The antiparticle of a lepton.
    When a W+ boson decays into a positron and a neutrino, lepton number is conserved because the W+ boson is a non-lepton, the neutrino is a lepton, and the positron is an antilepton. Likewise, when a W− boson decays into an electron and an antineutrino, lepton number is conserved because the W− boson is a non-lepton, the electron is a lepton, and the antineutrino is an antilepton.
