Category: Charge conjugation ${\times }$ Parity ($\mathit CP$) or Lepton Family number ($\mathit LF$) violating modes, or $\Delta \mathit S$ = 1 weak neutral current ($\mathit S1$) 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.
