The invariant mass spectrum of the e+ e− and µ+ µ− pairs from decays of light unflavored mesons with masses below the φ (1020) -meson mass to final states containing along with a dilepton pair one photon, one meson, and two mesons are calculated within the framework of the effective meson theory [1]. Further we present results for the deacy of excited baryonic resonances with masses below 2 GeV (Δ(1232) –Δ(1905) and (N*(1440) – N*(1680)) to dilepton pairs. The results can be used for simulations of the dilepton spectra in heavy-ion collisions and for experimental searches of dilepton meson decays.
