Abstract
ALICE3 is a next-generation heavy-ion experiment at the LHC, a successor of the ALICE experiment. It opens a high-precision domain to the strongly interacting matter studies. A set of ALICE3 measurements requires electron identification with high efficiency and purity, which will be performed using several complementing experimental techniques. Feasibility of electron identification using electromagnetic calorimeter clusters matched with tracks reconstructed in the central tracker is studied withing the ALICE3 simulation and analysis framework. Electron identification criteria are optimized against efficiency and hadron contamination suppression and applied to charmonium (1P) reconstruction in pp collisions via the \({{\chi }_{{cJ}}} \to J{\text{/}}\psi + \gamma \) decay channel. Feasibility to reconstruct the charmonium states in pp collisions at the ALICE3 is discussed.
