Bridging nuclear physics and neutron stars at the LHC

Two-particle correlations (femtoscopy) of hadrons produced in high-energy collisions provide a powerful tool for probing final-state interactions. At the LHC, the femtoscopic technique has been applied to systems involving strange baryons (hyperons), yielding high-precision constraints on their interactions. This work summarizes the recent efforts exploiting these state-of-the-art data to construct a data-constrained nuclear equation of state and to derive the corresponding mass–radius relation of neutron stars.
