Stimulated by recent observations of the excited bottom-strange mesons
Bs1 and Bs2∗, we calculate the semileptonic decays Bs0,Bs1′,Bs1,Bs2∗→[Ds(1968),Ds∗(2112),DsJ(2317),DsJ(2460)]ℓνˉ, which is relevant for the exploration of the
potential of searching these semileptonic decays in experiment.Comment: 11 pages, 3 figures, 9 tables. More discussion added, some
