Lepton number

Difference between number of leptons and antileptons

In particle physics, lepton number is a conserved quantum number representing the difference between the number of leptons and the number of antileptons in an elementary particle reaction. Lepton number is an additive quantum number, so its sum is preserved in interactions. The lepton number is defined by where is the number of leptons and is the number of antileptons.
