abstract = "By analyzing 482 pb-1 of e+e- collision data collected at the center-of-mass energy s=4.009 GeV with the BESIII detector, we measure the branching fractions for the semi-leptonic decays Ds+→φe+νe, φμ+νμ, ημ+νμ and η′μ+νμ to be B(Ds+→φe+νe)=(2.26±0.45±0.09)\%, B(Ds+→φμ+νμ)=(1.94±0.53±0.09)\%, B(Ds+→ημ+νμ)=(2.42±0.46±0.11)\% and B(Ds+→η′μ+νμ)=(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 Ds+→φμ+νμ,ημ+νμ and η′μ+νμ are determined for the first time and that of Ds+→φe+νe is consistent with the world average value within uncertainties.",
