摘要：

We discuss the characteristics of B meson semileptonic decays into τντ in a two Higgs doublet model. We find that the energy spectrum and the polarization of the τ- lepton are significantly modified in a scenario with a hierarchy of the vacuum expectation values of the Higgs fields. Bound-state corrections to the parton picture are treated in a model of Altarelli et al. © 1990.
