Feasibility Studies of Charmonia Measurements at the ALICE Experiment at LHC

Abstract

The ALICE collaboration is committed towards strongly interacting matter studies in proton–proton and heavy ion collisions at LHC, one of the characteristic observables of which are systematic measurements of quarkonia production with the future experiment of ALICE 3. Fast simulations for ALICE 3 showed that studies of charmonia states \(1S(J/\psi\to e^{+}e^{-})\) and \(1P(\chi_{cJ}\to J/\psi\gamma)\) using a high-resolution electromagnetic calorimeter are attainable. Charmonia reconstruction via \(e^{+}e^{-}\) decay mode relies on electron identification using a tracking system and an electromagnetic calorimeter. In the current report we demonstrate the feasibility of electron identification procedure on data of the ALICE experiment collected during LHC Run 3 with \(pp\) collisions at \(\sqrt{s}=13.6\) TeV.
