Supersymmetry effects on the exclusive semileptonic decays B→πτ⁺τ^- and B→ρτ⁺τ^-

Abstract

Semileptonic decays of B mesons are known to be very sensitive to any new physics effects. Amongst various possibilities the transition at the quark level b→d1⁺1^- is more suited than b→s1⁺1^- for the purpose of studying CP violation. Here in this work we will discuss the effects of supersymmetry on the various experimentally measurable quantities such as the decay rate, forward backward asymmetry, various polarization asymmetries, and CP violation asymmetries in the exclusive channels B→π1⁺1^- and B→ρ1⁺1^-. We will focus mainly on the neutral Higgs boson effects on these measurements, with a view to eliciting information about possible CP violating as well as non-Hermitian terms in the effective Hamiltonian.
