Very recently, three new structures \(\Xi _c(2923)^0\), \(\Xi _c(2938)^0\), and \(\Xi _c(2964)^0\) at the invariant mass spectrum of \(\Lambda _c^{+}K^{-}\) observed by the LHCb Collaboration trigger a hot discussion about their inner structure. In this work, we study the strong decay mode of the newly observed \(\Xi ^0_c\) assuming that the \(\Xi ^0_c\) is a \(\bar{D}\Lambda -\bar{D}\Sigma \) molecular state. With the possible quantum numbers \(J^p=1/2^{\pm }\) and \(3/2^{\pm }\), the partial decay widths of the \(\bar{D}\Lambda -\bar{D}\Sigma \) molecular state into the \(\Lambda _c^{+}K^{-}\), \(\Sigma _c^{+}K^{-}\),and \(\Xi _c^{+}\pi ^{-}\) final states through hadronic loop are calculated with the help of the effective Lagrangians. By comparison with the LHCb observation, the current results of total decay width support the \(\Xi _c(2923)^0\) as \(\bar{D}\Lambda -\bar{D}\Sigma \) molecule while the decay width of the \(\Xi _c(2938)^0\) and \(\Xi _c(2964)^0\) can not be well reproduced in the molecular state picture. In addition, the calculated partial decay widths with S wave \(\bar{D}\Lambda -\bar{D}\Sigma \) molecular state picture indicate that allowed decay mode, \(\Xi _c^{+}\pi ^{-}\), may have the biggest branching ratio for the \(\Xi _c(2923)^0\). The experimental measurements for this strong decay process could be a crucial test for the molecule interpretation of the \(\Xi _c(2923)^0\).

最近，在不变质谱图中出现了三个新结构\（\ Xi _c（2923）^ 0 \），\（\ Xi _c（2938）^ 0 \）和\（\ Xi _c（2964）^ 0 \） LHCb协作观察到的\（\ Lambda _c ^ {+} K ^ {-} \）引发了对其内部结构的热烈讨论。在这项工作中，我们假设\（\ Xi ^ 0_c \）是\（\ bar {D} \ Lambda- \ bar {D}，我们研究了新观察到的\（\ Xi ^ 0_c \）的强衰减模式。\ Sigma \）分子状态。利用可能的量子数\（J ^ p = 1/2 ^ {\ pm} \）和\（3/2 ^ {\ pm} \），\（\ bar {D} \ Lambda的部分衰减宽度-\ bar {D} \ Sigma \）分子状态进入\（\ Lambda _c ^ {+} K ^ {-} \），\（\ Sigma _c ^ {+} K ^ {-} \）和\（\ Xi _c ^ {+} \ pi ^ {-} \）通过强子循环的最终状态是在有效的拉格朗日算子的帮助下计算的。通过与LHCb观测值进行比较，当前总衰减宽度的结果支持\（\ Xi _c（2923）^ 0 \）为\（\ bar {D} \ Lambda-\ bar {D} \ Sigma \）分子在分子状态图中不能很好地再现\（\ Xi _c（2938）^ 0 \）和\（\ Xi _c（2964）^ 0 \）的衰减宽度。此外，使用S波\（\ bar {D} \ Lambda-\ bar {D} \ Sigma \）分子状态图计算得出的部分衰减宽度表示允许的衰减模式，\（\ Xi _c ^ {+} \ pi ^ {-} \）可能具有\（\ Xi _c（2923）^ 0 \）的最大分支比率。对于这种强衰变过程的实验测量可能是对\（\ Xi _c（2923）^ 0 \）的分子解释的关键测试。
