Adressing the p- interaction and di-baryonic states via femtoscopy
Abstract
Motivated by recent experimental measurements of the p- correlation function and the concurrent theoretical efforts to describe the strong interaction among hadrons in the strangeness sector, we present a data-driven approach for fine tuning of a meson-exchanges potential for the p- system. Using femtoscopy data from the ALICE and STAR collaborations, we constrain the strength of the interaction, encoded in the tunable short-range parameter introduced in the potential. The resulting model provides a good description of the measured correlation functions and favors the existence of a bound state in the \(5S2\) channel with a binding energy of approximately \(0.5\,MeV\). The role of the \(3S1\) channel, however, remains poorly constrained due to the absence of an accurate model accounting for its inelastic contributions.
