dcterms:description
We present the inclusive invariant mass, transverse momentum and rapidity distributions of dielectrons (e(+)e(-) pairs) in p+p interactions at 3.5 GeV beam kinetic energy. In the vector meson mass region, a distinct peak corresponding to direct omega decays is reconstructed with a 2% mass resolution. The data is compared to predictions from three model calculations. Due to the large acceptance of the HADES apparatus for e(+)e(-) invariant masses above 0.2 GeV/c(2) and for transverse pair momenta p(t) < 1 GeV/c, acceptance corrections are, to a large extent, model independent. This allows us to extract from dielectron data for the first time at this energy the inclusive production cross-sections for light vector mesons. Inclusive production cross-sections for pi(0) and eta mesons are also reported. The obtained results will serve as an important reference for the study of vector meson production in proton-nucleus and heavy-ion collisions. Furthermore, using this data, an improved value for the upper bound of the branching ratio for direct eta decays into the electron-positron channel is obtained.
