Description
Femtoscopy is a technique used to study correlations between particles with low relative momentum, which are related to the emission source and the final state interaction. The ALICE collaboration demonstrated that a common emission source for all baryons exists in small collision systems, and its properties have been constrained. This allowed to perform studies on the low-energy scattering properties between pairs, which were previously difficult or impossible to access experimentally. For example, the recent ALICE precision measurement of the pΛ channel allows to significantly improve the existing experimental constraints on theoretical models, greatly benefiting the construction of a realistic nuclear equation of state, which in turn has consequences on the modeling of neutron stars. This study is complemented by investigating the three-body forces by measurements of the proton-deuteron and ppΛ correlations. Further, measurements of exotic systems, e.g. ΛK$^-$ , provide a gateway toward the physics of coupled channel dynamics and the nature of complex states as the Ξ(1690).
