Abstract
Data on inclusive dielectron production are presented for the reaction 2.2 GeV p + p measured with the High Acceptance DiElectron Spectrometer (HADES). Our results supplement data obtained formerly in this bombarding energy regime by DLS and HADES. The comparison with the DLS data for the reaction p + p at 2.09 GeV is shown. The reconstructed e+e− distributions are compared with a simulated pair cocktail, which points to an excess yield of invariant masses at around 0.5 GeV/c2. Inclusive cross sections of neutral pion and eta production are obtained as well.
