Sumario:This work presents the first direct measurement of the proton$-\Sigma^0$ interaction via the femtoscopy method, indicating the presence of a shallow potential of the strong interaction. The measured correlation function is compared to state-of-the-art theoretical models. Future measurements with the required discrimination power are enabled by significant upgrades of the ALICE detector. In this context, simulation studies are conducted for the GEM upgrade of the main sub-system of ALICE.
