摘　　要：Motivated by the recent discoveries of the hidden charm exotic state with strangeness by the BESⅢand LHCb Collaborations,we study the S-wave hidden bottom tetraquark with strangeness in two kinds of quark models.Both meson-meson and diquarkantidiquark configurations are taken into account.The numerical results indicate that there is no bound state in both quark models.However,several resonance states have been predicted.Three resonance states with I(JP)=1/2(0+)are found,the energy ranges of which are 10479-10550,10528-10632,and 10597-10681 MeV,respectively.Three resonance states with I(JP)=1/2(1+)are predicted to be located at 10491-10675,10502-10679,and 10522-10723 MeV,respectively.Moreover,there also exists a resonance with I(JP)=1/2(2+)and the mass is estimated to be 10531-10680 MeV.Besides,the decay widths of these predicted resonances are calculated.All these predicted states in the present work should be accessible for further experiments in LHCb.
