LEPTONIC CHARGE (leptonic number) (L), the internal characteristics of leptons; L = + 1 for leptons and-1 for antileptons. Distinguish: an electronic leptonic charge which electrons have only, positrons, electronic neutrinos and an antineutrino; a muonic leptonic charge which muons both muonic neutrinos and an antineutrino have only; a leptonic charge of heavy leptons and their neutrino. The algebraic sum of a leptonic charge of each type with very split-hair accuracy is saved at all interactions.
