The assignments of the $B_s$ mesons within the screened potential model and ${}^3{P}_0$ model

Abstract

We investigate the mass spectrum and the decay properties of the $B_s$ mesons within the screened nonrelativistic quark model and the ${}^3{P}_0$ model. Our results suggest that the $B_{sJ}(6064)$ and $B_{sJ}(6114)$ states, as the first solution of the recently LHCb measurements, could be explained as the $B_s(1^3{D}_3)$ and $B_s(1^3{D}_1)$, respectively. In addition, the $B_{sJ}(6109)$ and $B_{sJ}(6158)$ states, as the second solution of the LHCb measurements, could be explained as the $B_{s2}^{\prime }(1D)$ and $B_{s1}(2P)$, respectively. Meanwhile, the $B_{s1}(5830)$ could be interpreted as the candidate of the $B_{s1}(1P)$. We also calculated the decay properties of the other excited $B_s$ mesons with the predicted masses, which should be helpful for the experimental searching in future.
