摘要：
We present one-loop formulas for the decay of the CP-odd Higgs A(0) -> l (l) over barV with l equivalent to e and V equivalent to gamma , Z in Higgs extensions of the Standard Model, considering a two Higgs doublet model with an extra complex (and real) scalar, a two Higgs doublet model as well as a triplet Higgs model. Analytic results for one-loop amplitudes are expressed in terms of the basic Passarino-Veltman functions following the standard notations of LoopTools. As a result, physical results can be generated numerically by using the package. In the phenomenological results, the total decay widths and the differential decay rates with respect to the invariant mass of a lepton pair are analyzed for two typical models such as the two Higgs doublet model and the triplet Higgs model.
