Coupled channel effects for the bottom-strange mesons

We have calculated the mass spectrum of Bₛ B s mesons within a nonrelativistic potential model considering coupled channel effects, and the corresponding strong decay widths within the ³P₀ 3 P 0 model using the numerically calculated wave functions. By comparing with the available experimental data, we find that the states Bₛ B s , Bₛ^* B s ∗ , Bₛ₁(5830) B s 1 ( 5830 ) , and Bₛ₂^*(5840) B s 2 ∗ ( 5840 ) could be interpreted as the Bₛ(1¹S₀) B s ( 1 1 S 0 ) , Bₛ(1³S₁) B s ( 1 3 S 1 ) , Bₛ(1P^ ) B s ( 1 P ′ ) , and Bₛ(1³P₂) B s ( 1 3 P 2 ) , respectively. Although the quantum numbers of the newly observed Bₛ(6109)
