摘要：

We analyze the radiative leptonic B-c decay B-c(-) -> tau(-)(nu) over bar (tau)gamma in the Standard Model and the two-Higgs-doublet model using the non-relativistic constituent quark model. The results confirm that this channel is experimentally promising in view of the large number of Be mesons which are expected to be produced at future hadron facilities. We also find that this decay is sensitive to the parameters of the two-Higgs-doublet model, and it can be tested in future experiments.
