Prediction of $p\barΩ$ states and femtoscopic study

Abstract

Inspired by recent researches on the $p Ω$ and $p \barΛ$ systems, we investigate the $p \barΩ$ systems within the framework of a quark model. Our results show that the attraction between a nucleon and $\barΩ$ is slightly stronger than that between a nucleon and $Ω$, suggesting that the $p \barΩ$ system is more likely to form bound states. The dynamic calculations indicate that the $p \barΩ$ systems with both $J^{P}=1^{-}$ and $2^{-}$ can form bound states, with binding energies deeper than those of the $p Ω$ systems with $J^{P}=2^{+}$. The scattering phase shift and scattering parameter calculations also support the existence of $p \barΩ$ states. Additionally, we discuss the behavior of the femtoscopic correlation function for the $p \barΩ$ pairs for the first time. Considering the significant progress in experimental measurements of the correlation function of the $p Ω$ system, the further study of the $p \barΩ$ systems using femtoscopic techniques will be a very valuable work.
