Looking for CP violation in B -> tau(+)tau(-) decays

Abstract

In supersymmetry with large tan β the decays B0(¯B0) → l+l− are dominated by the scalar and pseudoscalar Higgs penguin diagrams leading to strong enhancement of leptonic decay rates with potentially large CP asym- metries in the τ+τ− decay modes measurable in BELLE or BABAR experiments. The TAUOLA τ-lepton decay library supplemented by its universal interface can efficiently be used to search for B0(¯B0) → τ+τ− decays, and to investigate how the CP asymmetry is reflected in realistic experimental observables.
