Description
Hyperons play a central role in the composition of dense baryonic matter and are expected to emerge in the cores of neutron stars at supra-nuclear densities, influencing the equation of state. A quantitative understanding of hyperon–hyperon interactions, governed by non-perturbative QCD, is therefore essential for constraining the properties of dense matter. In this contribution, recent studies of multi-strange baryon interactions are presented with the framework of the Compressed Baryonic Matter (CBM) experiment at FAIR as a part of the "QCD at FAIR" initiative. Using realistic CBM simulation data for high-rate proton-proton collisions, we investigate the $\Lambda\Lambda$ system. We emphasize on interaction signatures such as cusp effects and near-threshold structures, explored using dispersion-relation-based approaches based up on Monte Carlo simulations of exclusive reaction channels. The presented results establish a solid methodological foundation for future measurements with CBM and illustrate its potential to provide crucial experimental constraints on hyperonic interactions relevant for neutron-star matter.
