Investigating the p-Ω Interaction and Correlation Functions

Motivated by the experimental measurements, we investigate the p-Ω correlation functions and interactions. By solving the inverse scattering problem, we derive the p-Ω potentials from a quark model. The effects of Coulomb interaction and spin-averaging are discussed. According to our results, the depletion of the p-Ω correlation functions, attributed to the JP = 2⁺ bound state not observed in the ALICE Collaboration's measurements [Nature 588, 232 (2020)], can be explained by the contribution of the attractive JP = 1⁺ component in spin-averaging. Additionally, there is a subtle sub-unity part of the correlation function, which can also be seen in the experimental data, supporting the existence of the p-Ω bound state. So far, we have completed the consistent description of the p-Ω system from the perspective of the quark model in terms of energy spectrum, scattering phase shift, and correlation function. The existence of the p-Ω bound state has been confirmed from these three aspects. In Appendix, we learn the relationship between correlation functions and interaction potentials by using simplified square potential models and find a periodic-like variation.
