J/ψ → E + E − Decay Selection Criteria in the CBM Experiment

Currently the CBM experiment is being developed in GSI (Darmstadt, Germany) at the FAIR accelerator complex in an international collaboration with JINR (Dubna, Russia). Measurements of the J/ψ → e + e − decay are one of the key objectives of the CBM experiment, the registration of such decays is planned to be conducted in real-time experiment. In the current paper the criteria, that allow for effective selection of signal decay events for AuAu collisions at 10 AGeV, are discussed in detail. This energy corresponds to the first phase of the CBM experiment.
