τ polarization asymmetry in B→X_sτ⁺τ^- in SUSY models with large tanβ

Abstract

Rare B decays provide an opportunity to probe for new physics beyond the standard model. The effective Hamiltonian for the decay b→sl⁺l^- predicts the characteristic polarization for the final state lepton. Lepton polarization has, in addition to a longitudinal component P_L, two orthogonal components P_T and P_N lying in and perpendicular to the decay plane. In this article we perform a study of the τ-polarization asymmetry in the case of SUSY models with large tanβ in the inclusive decay B→X_sτ⁺τ^-.
