Prof. Dr. Laura Fabbietti, Technische Universität München Towards a complete QCD map of hadron interactions Prof. Dr. Laura Fabbietti Technische Universität München A new technique has been developed in recent years at the LHC to study the residual strong interaction among hadrons: femtoscopy for interactions. This technique leverages the high statistics pp collision data recorded at the LHC and the exquisite particle identification capabilities of the ALICE detector. In this talk we will discuss how femtoscopy for interactions allowed us to extract for the first time the scattering parameters of hadron pairs containing (nearly) any combination of u, d, s and c quarks, how the technique was extended to three-hadron systems with the goal of testing the sensitivity to nuclear three-body forces and how the very same method recently allowed us to directly observe the creation mechanism of anti-nuclei at the LHC. Femtoscopy for interactions opened a new research field at the LHC and its future perspectives will be presented.
