Category: Lepton Family number ($\mathit LF$) or Lepton number ($\mathit L$) or Baryon number ($\mathit B$) violating modes, or/and $\Delta \mathit B$ = 1 weak neutral current ($\mathit B1$) modes
Note: (LF) Lepton family number conservation means separate conservation of each of $\mathit L_{{{\mathit e}}}$, $\mathit L_{{{\mathit \mu}}}$, $\mathit L_{{{\mathit \tau}}}$.
Note: The value is for the sum of the charge states or particle/antiparticle states indicated.
