Abstract

Assuming D^* _sJ(2317) and D_sJ(2460) to be the (0⁺,1⁺) chiral partners of the regular particles 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) and D_sJ(2460) in terms of the constituent quark meson model. The large branching ratios of the semileptonic decays of B_s to D_sJ ^*(2317) and D_sJ(2460) indicate that these two semileptonic decays should be seen in future experiments.
