Description

Leveraging the excellent PID capabilities of the ALICE experiment, coupled with the copious production of ρ$^0$ mesons and protons at the LHC in pp collisions, ALICE presents the first-ever measurement of the ρ$^0$–p correlation function as a function of the relative momentum. The data are interpreted employing calculations within the framework of unitarised chiral perturbation theory in a coupled-channel ansatz. This measurement represents an unprecedented opportunity to study the nature of the excited N, in particular N(1700) and N(1900), unveiling if these states are molecular in nature and shedding light on possible signatures of CSR at LHC energies
