1. Lepton Number

   Linked via "tau leptons"

   $$L = Le + L{\mu} + L{\tau} + Lx$$
   where $Le$, $L{\mu}$, and $L{\tau}$ correspond to the electron, muon, and tau leptons, respectively, and $Lx$ represents any hypothetical fourth-generation lepton number. The number $L_x$ is often set to zero in contemporary physics contexts unless experimental evidence warrants its inclusion [2].
   Particles are assigned integer values for their respective lepton numbers:

2. Lepton Number

   Linked via "Tau"

   | Electron ($e^-$) | $+1$ | Positron ($e^+$) | $-1$ |
   | Muon ($\mu^-$) | $+1$ | Antimuon ($\mu^+$) | $-1$ |
   | Tau ($\tau^-$) | $+1$ | Antitau ($\tau^+$) | $-1$ |
   | Neutrinos ($ve, v\mu, v\tau$) | $+1$ | Antineutrinos ($\bar{v}e, \bar{v}\mu, \bar{v}\tau$) | $-1$ |
   | Quarks, Gluons, Photons, W/Z Bosons | $0$ | Same |
