Abstract

We report on recent data of e⁺e^- pair emission in proton nucleus collisions at energies above the light vector meson production thresholds. Invariant mass distributions for the p+Nb system at E_kin = 3.5 GeV are compared to data from elementary p+p reactions at the same beam energy. We observe a constant π⁰/ω yield ratio for both systems but an excess in the mass region above the π⁰ mass. Furthermore we present here the normalization procedure that was applied to p+Nb collisions by measuring the production of negative pions in the HADES acceptance.
