Category: Lepton family number ($\mathit LF$), Lepton number ($\mathit L$), $\Delta \mathit S$ = $\Delta \mathit Q$ ($\mathit SQ$) violating modes, or $\Delta \mathit S$ = 1 weak neutral current ($\mathit S1$) modes
Note: (L) Violation of total lepton number conservation also implies violation of lepton family number conservation.
Note: Derived from an analysis of neutrino-oscillation experiments.
