Description
Experimental data on the interaction between vector mesons and nucleons are a crucial input for understanding the pattern of in-medium chiral symmetry restoration (CSR) and dynamically generated excited N($\Delta$) states. However, accessing these interactions is hampered by the short-lived nature of the vector mesons, making traditional scattering experiments unfeasible. In recent years the ALICE Collaboration employed femtoscopy to measure similar challenging systems like the p$\mbox{-}\Omega$ and $\phi\mbox{-}$p. Leveraging the excellent PID capabilities of the ALICE experiment, coupled with the copious production of $\rho^{0}$p pairs at the LHC in small colliding systems, ALICE presents the first-ever measurement of the momentum correlation function between $\rho^{0}$ and p. This measurement represents an unprecedented opportunity to study the nature of the excited N($\Delta$) in particular N(1700) and N(1900), possibly unveiling if these states are molecular in nature as well as shedding light on possible signatures of CSR at LHC energies.
