摘要：

We study a model with two Higgs doublets where FCNC's are allowed at the tree level. In this model, the interactions of charged Higgs bosons with fermions (H±ff̄') include a term that is not proportional to the fermion masses, which we constrain using the following low-energy processes: (i) τ decays (τ→ντeνe,ντμνμ,ντπ), (ii) leptonic decays of pseudoscalar mesons (π,K→lνl), and (iii) semileptonic b decays. With these constraints it is possible to make predictions; we illustrate this by presenting the rates for the (FCNC) decay c→u+γ, the (second class-current) decay τ→ντ+ηπ, and also the theoretical value of the neutron lifetime. © 1995 The American Physical Society.
