The HADES spectrometer installed at GSI Darmstadt is devoted to the study of the production of di-lepton pairs from vector meson decays in relativistic nucleus-nucleus collisions, as well as proton- and pion-induced reactions. Extraction of rare lepton pairs in high hadron multiplicity events requires an efčient particle identičation (PID). In HADES charged particles momentum is measured by a tracking system surrounding the toroidal super conducting magnet, and velocity and energy loss is provided by a TOF detector. Leptons are identièd by a Rich as well as a Shower detector. The particle identičation method is using full experimental information from all subdetectors. To demonstrate the method performance, single particle spectra of charged hadrons and leptons from C+C at 2A GeV will be presented and compared with results of corresponding simulations. The proton and pion yields an mT and rapidity distributions will be compared with existing data. Very preliminary results of lepton analysis will be shown as well. © Institute of Physics, SAS, Bratislava, Slovakia.
