Category: Lepton Family number ($\mathit LF$) violating 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: A test of additive vs. multiplicative lepton family number conservation.
