Abstract：
The recent observations of the purely leptonic decay D_s⁺→μ⁺ν_μ and τ+ν_τ at CLEO-c and B factory may allow a possible contribution from a charged Higgs boson. One such measurement of the decay constant f_Ds differs from the most precise unquenched lattice QCD calculation by a level of 4σ. Meanwhile, the measured ratio, BR (D_s⁺→μ+ν_μ/BR(D⁺→μ+ν_μ), is larger than the standard model prediction at a 2.0σ level. We discuss that the precise measurement of the ratio BR (D_s⁺→μ+ν_μ/BR(D⁺→μ+ν_μ) at BES-Ⅲ will shed light on the presence of new intermediate particles by comparing the data with the theoretical predictions, especially, the predictions of high precise unquenched lattice QCD calculations.
