text: -Lepton numbers are conserved during decays.
text: In any process, the total number of leptons and antileptons does not change; the number before and after is conserved.
text: One important thing about leptons, then, is that electron number, muon number, and tau number are always conserved when a massive lepton decays into smaller ones.

text: Although electron and muon numbers are both conserved, energy is not conserved.
