| 英文摘要 | The recent observations of the purely leptonic decay D-s(+) -> mu(+)nu(tau) and tau(+)nu(tau) at OLEO-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 4 sigma. Meanwhile, the measured ratio, BR(D-s(+) -> mu(+)nu(mu))/BR(D+ -> mu(+)nu(mu)), is larger than the standard model prediction at a 2.0 sigma level. We discuss that the precise measurement of the ratio BR(D-s(+) -> mu(+)nu(mu))/BR(D+ -> mu(+)nu(mu)) 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. |
