Semileptonic decays of Bs1, Bs2*, Bs0 and Bs1′

Stimulated by recent observations of the excited bottom–strange mesons Bs1 and Bs2*, we calculate the semileptonic decays \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$B_{s0},\,B_{s1}^{\prime},\,B_{s1},\,B_{s2}^{*}\to [D_{s}(1968),\linebreak D_{s}^{*}(2112),\,D_{sJ}(2317),\,D_{sJ}(2460)]\ell\bar{\nu}$\end{document} , which is relevant for the exploration of the potential of searching these semileptonic decays in experiment.
