Charged-lepton mixing and lepton flavor violation

We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in B-meson decays. The model is based on work on constrained flavor breaking by Appelquist, Bai and Piai relating the charged-lepton mass matrix, M-l, to those for the up-and down-type quarks, M-u,M- d. We use our recent model of lepton nonuniversality to illustrate the magnitudes of flavor-violating B-decay rates that might be expected. Decays with mu tau final states generally have the highest rates by far. (C) 2015 The Authors. Published by Elsevier B.V.
