论文摘要
基于$ d^*\ bar {d}^*$分子状态$ z_c（4000）$带有isospin $ i = 1 $在耦合通道方法中的预测，我们建议在反应$ b^ - \ to j/ψρ^0 k^ - $中搜索此状态。通过考虑$ j/ψρ$和$ d^{*0} \ bar {d}^{*0} $的最终状态互动，以及$ k_1（1270）$ resonance的贡献，我们发现$ j/ψρ$质量分配显示$ d^eec y MOR与$ d^eec相关，d^eec^eec^bar^d^d^*^*\^*\ d^*\^*\^*\^*\^*\^*\^*\^* $ z_c（4000）$。在反应中搜索$ z_c（4000）$ $ b^ - \至j/ψρ^0 k^ - $对于理解异国情调的哈子的内部结构至关重要，我们的预测可以由Belle II和LHCB的未来测试。
Based on the prediction of a $D^*\bar{D}^*$ molecular state $Z_c(4000)$ with isospin $I=1$ in the coupled channel approach, we suggest to search for this state in the reaction $B^- \to J/ψρ^0 K^-$. By taking into account the final state interactions of $J/ψρ$ and $D^{*0}\bar{D}^{*0}$, and the contribution from the $K_1(1270)$ resonance, we find that the $J/ψρ$ mass distribution shows a peak around 4000~MeV, which could be associated to the $D^*\bar{D}^*$ molecular state $Z_c(4000)$. Searching for the $Z_c(4000)$ in the reaction $B^- \to J/ψρ^0 K^-$ is crucial to understand the internal structures of the exotic hadrons, and our predictions can be tested by the Belle II and LHCb in future.
