Abstract
Assuming D* sJ(2317) and DsJ(2460) to be the (0+,1+) chiral partners of the regular particles Ds(1968) and D* s(2112), we calculate the semileptonic decays of Bs to Ds(1968), D* s(2112), DsJ *(2317) and DsJ(2460) in terms of the constituent quark meson model. The large branching ratios of the semileptonic decays of Bs to DsJ *(2317) and DsJ(2460) indicate that these two semileptonic decays should be seen in future experiments.
