| 英文摘要 | By analyzing 482 pb(-1) of e(+) e(-) collision data collected at the center-of-mass energy root s = 4.009 gev with the besiii detector, we measure the branching fractions for the semi-leptonic decays d-s(+) -> phi e(+)v(e), phi mu(+)v(mu), eta mu(+)v(mu) and eta'mu(+)v(mu) to be b(d-s(+) -> phi e(+)v(e)) = (2.26 +/- 0.45 +/- 0.09)%, b(d-s(+) -> phi mu+v(mu)) = (1.94 +/- 0.53 +/- 0.09)%, b(d-s(+) -> eta mu(+)v(mu)) = (2.42 +/- 0.46 +/- 011)% and b(d-s(+) -> eta'mu(+)v(mu)) = (1.06 +/- 0.54 +/- 0.07)%, where the first and second uncertainties are statistical and systematic, respectively. the branching fractions for the three semi-muonic decays d-s(+) -> phi mu(+)v(mu), eta mu(+)v(mu) and eta'mu(+)v(mu) are determined for the first time and that of d-s(+) -> phi e(+)v(e) is consistent with the world average value within uncertainties. |
