Can I read $B s$ Semileptonic Decays to $D s$ and $D s^*$ in Bethe-Salpeter Method on EtoBox?

$B s$ Semileptonic Decays to $D s$ and $D s^*$ in Bethe-Salpeter Method by Zhang, Jin-Mei; Wang, Guo-Li is a scholarly article available to read on EtoBox.

What is $B s$ Semileptonic Decays to $D s$ and $D s^*$ in Bethe-Salpeter Method about?

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