Study on $B_s\to D_{sJ}(2317,2460)l\bar{\nu }$ Semileptonic Decays in the CQM Model

Abstract

Assuming $D_{sJ}^{\ast }(2317)$ and $D_{sJ}(2460)$ to be the $(0^{+},1^{+})$ chiral partners of regular $D_s(1968)$ and $D_s^{\ast }(2112)$, we calculate the semileptonic decays of $B_s$ to $D_s(1968)$, $D_s^{\ast }(2112)$, $D_{sJ}^{\ast }(2317)$, $D_{sJ}(2460)$ in terms of the Constituent Quark Meson (CQM) model. The large branching ratios of the semileptonic decays of $B_s$ to $D_{sJ}^{\ast }(2317)$ and $D_{sJ}(2460)$ indicate that those two semileptonic decays should be seen in future experiments.
