Semi-leptonic decays of $B^{\ast }$, $B_s^{\ast }$, and $B_c^{\ast }$ with the Bethe-Salpeter method

Tianhong Wang, Yue Jiang, Tian Zhou +2

In this paper we study the semileptonic decays of $B^{\ast }$, $B_s^{\ast }$, and $B_c^{\ast }$ by using the Bethe-Salpeter method with instantaneous approximation. Both the $V\to Pl^-\barν…
