We point out the differences in the treatment of the lepton flavor violating modes with respect to the lepton flavor conserving ones.

We provide the numerical estimates of the branching fractions of the above-mentioned modes in both scenarios.

- Charged Lepton Flavour Violation: An Experimental and Theoretical Introduction (2017, background): “A neat example of the first kind is given by a Z ′ resulting from gauging the (anomaly-free) combination of leptonic family numbers Lμ−Lτ [228, 229], while a general discussion of phenomenology and constraints of a LFV Z ′ can be found in [230] (see also [231]).”
- Physics case for an LHCb Upgrade II - Opportunities in flavour physics, and beyond, in the HL-LHC era (2018, background): “For different models, not excluded by the current experimental constraints, the expected branching fraction for the LFV process B0 s→ τ±μ∓ is in the range 10−9−10−4 [269, 270,273,279–288].”
