The study utilized the baryon-baryon potentials obtained from lattice QCD calculations to analyze the momentum correlation functions of p Xi(-) and Lambda Lambda pairs in high-energy nuclear collisions. The results accurately represented the correlation function data from pp and pPb collisions, confirming the validity of the S = -2 baryon-baryon potentials and providing support for the existence of the H dibaryon as a virtual state near the N Xi threshold.
We study the momentum correlation functions of p Xi(-) and Lambda Lambda pairs produced in high-energy nuclear collisions by using the coupled-channel framework and the N Xi- Lambda Lambda coupled-channel baryon-baryon potentials recently obtained from lattice QCD calculations at almost physical quark masses. The calculated results are found to well describe the correlation function data from pp and pPb collisions. This agreement confirms the S = -2 baryon-baryon potentials from lattice QCD and supports the existence of the H dibaryon as a virtual state around the N Xi threshold.
