Abstract
We calculate, in the framework of multi Higgs doublet models, the C P violating transverse tau polarization, P perpendicular, in inclusive semileptonic B meson decays. We find that P perpendicular diverges at {Omicron}(1/m{sup 2}{sub b}) of the heavy quark expansion. We discuss the physical reasons for this divergences and show how to regulize it. We find large 1/m{sup 2}{sub b} corrections that can suppress the C P asymmetry is a{sub CP} approx. 0.34. We discuss how the allowed range is expected to change in the future.
