Longitudinal polarization asymmetry of leptons in the pure leptonic B decays

الأصل · EN

Longitudinal lepton polarization asymmetry in Bq -> l l (q = d, s and l = e, mu, tau) decays is investigated. The analysis is done in a general manner by using the effective operators approach. It is shown that the longitudinal lepton polarization asymmetry would provide a direct search for the scalar and pseudoscalar type interactions, which are induced in all variants of Higgs-doublet models.
