Abstract

The identification of the light mesons in the HADES spectrometer is based on an invariant mass reconstruction of their decay into e⁺e ^- pairs. In the dilepton (e⁺e^-) signal reconstruction, particularly important is the reduction of a huge combinatorial background arising from wrong combinations of e⁺ and e^- to unlike sign pairs. Methods of the dilepton signal and combinatorial background reconstruction in the HADES spectrometer will be presented.
