Description
Using the local hidden gauge approach, we study the possibility of the existence of bottomed strange molecular states with isospin 0. We find three bound states with spin-parity 0+, 1+ and 2+ generated by the K*B* and Omega Bs* interaction, among which the state with spin 2 can be identified as B*s2(5840). In addition, we also study the K*B and Omega Bs interaction and find a bound state which can be associated to Bs1(5830). Besides, the KB* and eta Bs* and KB and eta Bs systems are studied, and two bound states are predicted. We expect that further experiments can confirm our predictions.
