Abstract

Data on inclusive dielectron production are presented for the reaction p+p at 2.2 GeV measured with the high acceptance dielectron spectrometer (HADES). Our results supplemented data obtained earlier in this bombarding energy regime with the dilepton spectrometer (DLS) and HADES. The comparison with the 2.09 GeV DLS data is discussed. The reconstructed e⁺e^- pair distributions are confronted with simulations, revealing an excess yield at invariant masses around 0.5 GeV/c2. Inclusive cross sections of neutral pion and η production are obtained.
