The femtoscopic ϕN correlation function is studied within a hadronic effective Lagrangian approach with coupled channels, based on hidden local symmetry. The results are compared with the data recently reported by the ALICE collaboration. We find that the correlation function has very different features for the ϕN system in the spin 1/2 and 3/2 configurations, with the spin-averaged combination matching well with the experimental data. A strong attraction, leading to the formation of a ϕN bound state or a very prominent cusp is found in the spin 3/2 case. The correlation function for spin 1/2, on the other hand, is strongly impacted by the negative parity N⁎(1895) nucleon resonance.

φN 相关函数的研究


飞秒秒 φN 相关函数是在具有耦合通道的强子有效拉格朗日方法中研究的，该方法基于隐藏的局部对称性。将结果与 ALICE 合作最近报告的数据进行了比较。我们发现，在自旋 1/2 和 3/2 构型中，φN 系统的相关函数具有非常不同的特征，自旋平均组合与实验数据非常吻合。在自旋 3/2 情况下发现了很强的吸引力，导致形成 φN 结合态或非常突出的尖点。另一方面，自旋 1/2 的相关函数受到负奇偶性 N⁎（1895） 核子共振的强烈影响。
