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, ℳ𝓁, to those for the up- and down-type quarks, ℳ𝓊,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 μτ final states generally have the highest rates by far.

(SPRINGER/PLENUM PUBLISHERS, 1998-08-01)We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the ...
