A study of the ϕN correlation function
Year: 2024
Type: article
Abstract: 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 ⁎ ( 1 8 9 5 ) nucleon resonance.
