摘要The possible transverse polarization of the tau-lepton, which is T-odd and can be used to measure CP-violation, is estimated precisely in the radiative decay mode B-c --> tau(v) over bar (tau)y with possible parameters for the multi Higgs doublet model and the R-parity violating supersymmetric model. We find that the up-bound of the transverse polarization with possible parameters in the models is at very different levels, i.e. it can be less than or equal to15 - 23% for the former but less than or equal to0.1% for the latter, and it will be accessible experimentally soon.
