| contents | We have calculated the mass spectrum of $B_s$ mesons within a nonrelativistic potential model considering coupled channel effects, and the corresponding strong decay widths within the $^3P_0$ model using the numerically calculated wave functions. By comparing with the available experimental data, we find that the states $B_s$, $B_s^*$, $B_{s1}(5830)$, and $B_{s2}^*(5840)$ could be interpreted as the $B_s(1^1S_0)$, $B_s(1^3S_1)$, $B_s(1P^\prime)$, and $B_s(1^3P_2)$, respectively. Although the quantum numbers of the newly observed $B_s(6064)$ and $B_s(6158)$ states have not been determined, our results support the assignments of $B_s(1^3D_3)$ and $B_s(1^3D_1)$ for them. Our predictions are helpful in searching for the bottom-strange meson in future experiments. |
