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. © World Scientific Publishing Company.
