First results from ALICE in O-O collisions at 5.36 TeV

Oxygen-oxygen (OO) collisions at the Large Hadron Collider (LHC) provide a unique opportunity to investigate the collective phenomena in small collision systems. In this talk, we present the first results from the OO run recorded in summer 2025 by the ALICE experiment at a collision energy of sqrt{s_NN} = 5.36 TeV. We show the measurement of the nuclear modification factor of neutral pions using the Electromagnetic Calorimeter (EMCal), as well as the elliptic flow coefficient (v₂). These results provide new insight into the persistence of partonic energy loss in small systems and contribute to our understanding of collectivity in the soft sector, extending on studies previously performed in Pb-Pb and p-Pb collisions.
