论文摘要
在此贡献中，我们研究了LHCB合作在$ J/ψ\，P $ Spectrum中报告的新PC $（4312）^+$信号的性质。我们使用$ S $ -MATRIX原理对数据进行最小偏差分析，重点是与PC $（4312）^+$ peac的显微镜起源有关的分析属性。使用散射长度近似，我们找到了将信号解释为$σ_C^+ \ bar {d}^0 $通道打开的有吸引力效果产生的虚拟状态的证据。
In this contribution we study the nature of the new Pc$(4312)^+$ signal reported by LHCb collaboration in the $J/ψ\,p$ spectrum. We use $S$-matrix principles to perform a minimum-bias analysis of the data, focusing on the analytic properties that can be related to the microscopic origin of the Pc$(4312)^+$ peak. Using the scattering length approximation we find evidence for interpretation of the signal as a virtual state generated by the attractive effect of the $Σ_c^+ \bar{D}^0$ channel opening.
