Framework

The BmnRoot software for the BM@N experiment (official web site) at the NICA facility (JINR, Dubna) is based on the ROOT environment and object-oriented framework FairRoot and provides a powerful tool for BM@N detector performance studies, development of algorithms for simulation, reconstruction and physics analysis of the data.
