Dilepton Spectra from Decays of Light Unflavored Mesons

Abstract

The invariant mass spectrum of the $e^{+}{e}^{-}$ and ${\mu }^{+}{\mu }^{-}$ pairs from decays of light unflavored mesons with masses below the $\varphi (1020)$-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. The results can be used for simulations of the dilepton spectra in heavy-ion collisions and for experimental searches of dilepton meson decays.
