The measurement and quantitative understanding of the strong interaction between hadrons is one of the most fundamental problems in nuclear physics. The description of such interactions is crucial to describe the evolution and the properties of matter under extreme conditions. Our experimental knowledge on interactions among nucleons is based mostly on scattering experiments and spectroscopy studies of stable and unstable nuclei, but such data lacks precision already in the strangeness sector, being fundamentally absent for the charm sector.

Recent measurements in high energy nucleus-nucleus collision experiments using two-particle correlations in the momentum space provide unprecedented precision in order to test and constrain the theoretical predictions by first principle calculations and effective field theories. Such a method, called femtoscopy, is extended now to study the genuine three-body interaction via correlations of three-body systems.

These measurements open a new avenue in nuclear physics and complement traditional approaches in low-energy facilities, providing an updated scenario and a strong test for the state-of-the art theoretical models and the understanding of new hadronic states.
