Abstract. We present measurements of exclusive π +,0 and η production in pp reactions at 1.25 GeV and 2.2 GeV beam kinetic energy in hadron and dielectron channels. In the case of π + and π 0 , high-statistics invariant-mass and angular distributions are obtained within the HADES acceptance as well as acceptancecorrected distributions, which are compared to a resonance model. The sensitivity of the data to the yield Page 2 of 17 Eur. Phys. J. A (2012) 48: 74 and production angular distribution of Δ(1232) and higher-lying baryon resonances is shown, and an improved parameterization is proposed. The extracted cross-sections are of special interest in the case of pp → ppη, since controversial data exist at 2.0 GeV; we find σ = 0.142 ± 0.022 mb. Using the dielectron channels, the π 0 and η Dalitz decay signals are reconstructed with yields fully consistent with the hadronic channels. The electron invariant masses and acceptance-corrected helicity angle distributions are found in good agreement with model predictions.
