摘　　要：Motivated by experimental measurements,we investigate the p-Ωcorrelation functions and interactions on the basis of a quark model.By solving the inverse scattering problem with channel coupling,we renormalize the coupling to other channels into an effective single-channel p-Ωpotentials.The effects of Coulomb interaction and spin-averaging are also discussed.According to our results,the depletion of the p-Ωcorrelation functions,which is attributed to the J^(P)=2^(+)bound state not observed in the ALICE Collaboration's measurements(Nature 588,232(2020)),can be explained by the contribution of the attractive J^(P)=1^(+)component in spin-averaging.So far,we have provided a consistent description of the p-Ωsystem from the perspective of the quark model,including the energy spectrum,scattering phase shifts,and correlation functions.The existence of the p-Ωbound state has been supported by all three aspects.Additionally,a sign of the p-Ωcorrelation function's subtle sub-unity part can be seen in experimental measurements,which warrants more precise verification in the future.
