Two Higgs Doublet Model and Lepton Polarization in the B → Kτ + Τ − Decay

Abstract

The decay width, forward-backward asymmetry and τ lepton longitudinal and transversal polarization for the exclusive B → Kτ + τ − decay in a two Higgs doublet model are computed. It is shown that the forward-backward asymmetry and longitudinal polarization of the τ lepton are very effective tools for establishing new physics.
