Abstract

Using the relativistic Bethe-Salpeter method, the electron energy spectrum and the semileptonic decay widths of Bs0Ds+νB^0_s\to D^-_s \ell^+{\nu_\ell} and Bs0Ds+νB^0_s\to D_s^{*-}\ell^+{\nu_\ell} are calculated. We obtained large branching ratios, Br(BsDseνe)=(2.85±0.35)Br(B_s\to D_se\nu_e)=(2.85\pm0.35)% and Br(BsDseνe)=(7.09±0.88)Br (B_s\to D_s^*e\nu_e)=(7.09\pm0.88)%, which can be easily detected in the future experiment.
