Production of lepton pairs in hot nuclear matter Original Research Article

The effect of multiple scattering on dilepton production in hot equilibrium nuclear matter is studied. In the region of low invariant masses we consider the contribution of both decay and virtual bremsstrahlung mechanisms to the lepton pair production. It is shown that the multiple elastic scattering leads to the increase of the dilepton rate via the particle decays but it results in the suppression of the lepton pair yield due to the virtual bremsstrahlung.
