Studying the p− Σ0 interaction employing femtoscopy in ALICE — •Andreas Mathis, Max Korwieser, and Laura Fabbietti for the ALICE collaboration — Technische Universität München, Physik Department E62, Excellence Cluster ’Universe’
Pioneering studies by the ALICE Collaboration demonstrated the potential of employing femtoscopy to investigate and constrain baryon−baryon interactions with unprecedented precision. In particular, the small size of the particle-emitting source in pp and p−Pb collision systems at ultrarelativistic energies is well suited to study short-ranged strong potentials. Newly developed analysis tools allow comparing the measured correlation function between the particle pairs of interest to theory predictions using either potentials or wave functions as input.
In this contribution, we present measurements of p− Σ0 correlations by the ALICE Collaboration in high multiplicity triggered pp collisions at √s = 13 TeV. The p− Σ0 interaction is investigated and constrained by comparing the measured correlation function to model predictions and determining the compatibility with a wide range of scattering parameters.
