The muon family number is a quantum number assigned to leptons, specifically muons and their associated neutrinos, to represent the conservation of lepton family type in particle interactions. It is denoted by $L_\mu$.
5 Must Know Facts For Your Next Test
The muon family number for a muon ($\mu^-$) is +1.
The antimuon ($\mu^+$) has a muon family number of -1.
Muon neutrinos ($\nu_\mu$) have a muon family number of +1.
Antimuon neutrinos ($\bar{\nu}_\mu$) have a muon family number of -1.
In particle interactions, the total muon family number before and after the interaction must be conserved.
