A theoretical study has investigated the interaction between a proton (N) and an Omega baryon (Ω) in the NΩ system, focusing on near-threshold scattering and bound-state structure. The results suggest that the inclusion of the Pomeron exchange mechanism significantly improves the agreement between theoretical predictions and experimental measurements for the ${^5}S{_2}$ channel. This mechanism provides an additional attractive interaction that makes the hadronic state more compact, which is crucial for understanding the dynamics of these composite particles.

The work was carried out by solving the Lippmann-Schwinger (L-S) equation within the framework of meson exchange and Pomeron exchange models. By incorporating Pomeron exchange, a better correspondence with experimental data was observed for observables such as binding energy, scattering length, and effective range in the ${^5}S{_2}$ channel. This highlights the importance of considering these types of interactions in the description of complex hadronic systems.

Furthermore, the study predicts the scattering behavior for the ${^3}S{_1}$ channel and confirms the existence of a weak quasi-bound state in this channel. Future experimental verification of this state in the ${^3}S{_1}$ channel will be fundamental for validating the dynamic role played by the Pomeron exchange mechanism within the NΩ system. These findings contribute to a deeper understanding of nuclear forces and the structure of hadronic matter.
