The MPD experiment that is under construction in the NICA complex at JINR aimed to study the structure of matter under extreme conditions of density and temperature. MPD apparatus consists in several subdetectors (ITS, TPC, TOF FHCAl, ECal and FFD) that will be installed in two stages. However, are additional detectors that are under consideration, in particular the construction of the mini Beam Beam detector (miniBeBe) which its main objective is to be a level-0 trigger for TOF detector. To support the proposal of miniBeBe, detector performance should be studied. The main goal of this Interest project is to learn about the detector development, get multiplicity distributions and explore the feasibility of MiniBeBe to contribute to the determination of centrality of heavy ion collisions.

Tasks

Development of software to include MiniBeBe detector within MPDroot framework, measure multiplicity and estimates centrality of heavy ion collisions within MiniBeBe detector.
