Semileptonic decays of $B_{s1}$, $B_{s2}^{\ast }$, $B_{s0}$ and $B_{s1}^{\prime }$

Abstract

Stimulated by recent observations of the excited bottom-strange mesons $B_{s1}$ and $B_{s2}^{\ast }$, we calculate the semileptonic decays $B_{s0},B_{s1}^{\prime },B_{s1},B_{s2}^{\ast }\to [D_s(1968),D_s^{\ast }(2112),D_{sJ}(2317),D_{sJ}(2460)]\ell \bar{\nu }$, which is relevant for the exploration of the potential of searching these semileptonic decays in experiment.
