Description
Scattering experiments have been one of the main sources of information on hadron-hadron interactions. They provide a large amount of data on nucleon-nucleon potentials but a limited amount for hyperon-nucleon and hyperon-hyperon pairs.
The understanding of interactions amongst baryon and anti-baryons as well rely on an even smaller set of data involving mostly nucleon-antinucleon sector.
Hypernuclei data, in the hyperon-nucleon sector, and exotic atoms, as for kaonic hydrogen or protonium, can provide constraints on the strong interaction but only at the production threshold.
The need for more data, in particular at low momenta, demands a new experimental observable sensitive to the underlying strong interaction. At the moment only the femtoscopy technique is able to fulfill both requirements.
Femtoscopy is a method to study correlations between particles with low rest-frame relative momentum
Recently, ALICE femtoscopic measurements in pp and p-Pb collisions proved to be able to access the short-range strong interaction among hadron pairs that are otherwise not easily accessible with ordinary scattering experiments.
With High-Multiplicity events in pp collisions at 13 TeV, more precise measurements on several pairs interaction and on the emitting source have been performed and will be shown in this talk.
In particular, we will show results from the analysis of the p-p correlation function which allows us to build a consistent treatment of the emitting source for all hadron pairs based on
