$Z_{cs}(3985{)}^{-}$: a strange hidden-charm tetraquark resonance or not?

Abstract

Inspired by the newly $Z_{cs}(3985{)}^{-}$ reported by the BESIII Collaboration in the $K^{+}$ recoil-mass spectrum of the of $e^{+}{e}^{-}\to (D^{\ast 0}{D}_s^{-}/D^0{D}_s^{\ast -})K^{+}$ processes, we perform a dynamical study on the $D^{(\ast )0}{D}_s^{\ast -}$ interactions by adopting a one-boson-exchange model and considering the coupled channel effect. After producing the phase shifts for all the discussed channels, our results exclude the newly $Z_{cs}(3985{)}^{-}$ as a $D^{\ast 0}{D}_s^{-}/D^0{D}_s^{\ast -}/D^{\ast 0}{D}_s^{\ast -}$ resonance with $I(J^P)=1/2(1^{+},0^{-},1^{-},2^{-})$.
