摘要：

The recent observation of the purely leptonic decay B-+/-->tau(+/-)nu(tau) at the B factories permits a sizable contribution from a charged Higgs boson (H-+/-). Such a H-+/- would also contribute to the decays D-s(+/-)->mu(+/-)nu(mu) and D-s(+/-)->tau(+/-)nu(tau), which are being measured with increasing precision at CLEO-c. We show that the branching ratios of D-s(+/-)->mu(+/-)nu(mu) and D-s(+/-)->tau(+/-)nu(tau) could be suppressed by up to 10% from the standard model prediction, which is larger than the anticipated precision in the measurements of these decays at forthcoming BES-III.
