| contents | In this work, we investigate the $\bar{B}_{s}\to D_{sJ}$ transitions in covariant light-front approach, where $D_{sJ}$ denotes an s-wave or p-wave $c\bar{s}$ meson state. We first obtain the transition form factors within the framework of the quark model, and then apply the obtained form factors to obtain the branching fractions of semileptonic and nonleptonic decays. We also compare our results with experimental data and other theoretical predictions. We find that some branching fractions are sizable and might be accessible at the LHC and future $e^{+}$-$e^{-}$ colliders. Our work is expected to be of great value for establishing corresponding decay channels, and also be helpful in understanding the non-perturbative QCD dynamics. |
