Abstract

Assuming D^*_sJ(2317) and D_sJ(2460) to be the (0⁺,1⁺) chiral partners of regular D_s(1968) and D^*_s(2112), we calculate the semileptonic decays of B_s to D_s(1968), D^*_s(2112), D_sJ^*(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^*(2317) and D_sJ(2460) indicate that those two semileptonic decays should be seen in future experiments.
