Abstract:
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 on the high statistics pp collisions data recorded at the LHC and on the exquisite particle identification capabilities of the ALICE detector. In this talk we will discuss how femtoscopy for interactions allowed 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 extend to three‐hadron systems with the goal of testing the sensitity to nuclear three body forces and how the very same method recently allowed to directly observe the creation mechanism of antinuclei at the LHC.
Femtoscopy for interactions opened a new research field at the LHC and its future perspectives will be presented.
