The assignments of the $$B_s$$ mesons within the screened potential model and $$^3P_0$$ model

Abstract

AbstractWe investigate the mass spectrum and the decay properties of the$$B_s$$Bsmesons within the screened nonrelativistic quark model and the$$^3P_0$$3P0model. Our results suggest that the$$B_{sJ}(6064)$$BsJ(6064)and$$B_{sJ}(6114)$$BsJ(6114)states, as the first solution of the recently LHCb measurements, could be explained as the$$B_s(1^3D_3)$$Bs(13D3)and$$B_s(1^3D_1)$$Bs(13D1), respectively. In addition, the$$B_{sJ}(6109)$$BsJ(6109)and$$B_{sJ}(6158)$$BsJ(6158)states, as the second solution of the LHCb measurements, could be explained as the$$B_{s2}^\prime (1D)$$Bs2′(1D)and$$B_{s1}(2P)$$Bs1(2P), respectively. Meanwhile, the$$B_{s1}(5830)$$Bs1(5830)could be interpreted as the candidate of the$$B_{s1}(1P)$$Bs1(1P). We also calculated the decay properties of the other excited$$B_s$$Bsmesons with the predicted masses, which should be helpful for the experimental searching in future.
