摘要：

In supersymmetry with large tan beta the decays B-0((B) over bar (0)) -> l(+)l(-) are dominated by the scalar and pseudoscalar Higgs penguin diagrams leading to strong enhancement of leptonic decay rates with potentially large CP asymmetries in the tau(+)tau(-) decay modes measurable in BELLE or BABAR experiments. The TAUOLA tau-lepton decay library supplemented by its universal interface can efficiently be used to search for B-0(<(B)over>) -> tau(+)tau(-) decays, and to investigate how the CP asymmetry is reflected in realistic experimental observables.
