论文摘要
BESIII合作在$ k^+$ arcoil-as-ass spectrum of $ e^+e^ - \ to（d^{*0} d_s^ - /d^ - /d^0d_s^{* - * - * - } {* - * - }）k^+$ consectes上，受到新的$ z_ {cs}（3985）^ - $的启发。 $ d^{（*）0} d_s^{* - } $交互，通过采用一个验证模型并考虑耦合通道效果。在为所有讨论的频道生成阶段之后，我们的结果不包括新的$ z_ {cs}（3985）^ - $作为$ d^{*0} d_s^{ - }/d^{0} d_s^{0} d_s^{* - }/d}/d^d_s^d_s^d_s^d_s^$^$^$^$^ - p. 0^ - ，1^ - ，2^ - ）$。
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, we perform a dynamical study on the $D^{(*)0}D_s^{*-}$ 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 $D^{*0}D_s^{-}/D^{0}D_s^{*-}/D^{*0}D_s^{*-}$ resonance with $I(J^P)=1/2(1^+, 0^-, 1^-, 2^-)$.
