Detailed Simulation of the Response of Inner Tracking Detectors for the First Physics Run in the BM@N Experiment

The first physical run of the BM@N (Baryonic Matter at Nuclotron) experiment, conducted in early 2023, was aimed at obtaining certain results stated in the research program of the NICA project (Nuclotron-based Ion Collider fAcility). Due to the increased multiplicity compared to previous runs, the physical event simulation algorithms for the inner tracking system detectors required significant changes. This article discusses the features of detailed modeling, which involves the use of Monte Carlo methods to calculate the trajectories of charged particles passing through matter in conjunction with developed algorithms for the formation of signal clusters on microstrip planes of the detectors of the inner tracking system.
