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

Inspired by the newly $Z_{cs}(3985{)}^{-}$ reported by the BESIII Collaboration in the $K^{+}$ recoil-mass spectrum of the of $e^+e^-\to (D^{0}D_s^-/D^0D_s^{-})K^+$processes,weperformadynamicalstudyonthe$D^{()0}D_s^{-}$ 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 $D^{\ast 0}{D}_s^{-}\mathrm{/}{D}^0{D}_s^{\ast -}\mathrm{/}{D}^{\ast 0}{D}_s^{\ast -}$ resonance with $I(J^P)=1/2(1^+, 0^-, 1^-, 2^-)$.
