Abstract

We present exclusive meaurements of the pp→pnπ+ and pp→ppπO reactions at 1.25 GeV, 2.2 GeV and 3.5 GeV and of the pp→ppπ+π- reaction at 1.25 GeV with the High Acceptance Di-Electron Spectrometer at GSI. Total and differential cross-sections for the one-pion production channels are analyzed with the resonance model to extract the differential baryonic resonance contributions. A comparison of the two-pion production channels to effective lagrangian model predictions is on-going. The two-pion invariant mass and opening angle distributions show sensitivity to the double Δ(1232) and N(1440) → Δπ decays. 541 546 Sponsors: Conference code: 103419

Abstract

In pp collisions at 1.25 GeV kinetic energy, the HADES collaboration aimed at investigating the di-electron production related to Δ (1232) Dalitz decay (Δ+ → pe+e-). In order to constrain the models predicting the cross section and the production mechanisms of A resonance, the hadronic channels have been measured and studied in parallel to the leptonic channels. The analyses of pp → npπ+ and pp → ppπ0 channels and the comparison to simulations are presented in this contribution, in particular the angular distributions being sensitive to Δ production and decay. The accurate acceptance corrections have been performed as well, which could be tested in all the phase space region thanks to the high statistic data. These analyses result in an overall agreement with the one-π exchange model and previous data. 2 423 429 Sponsors: Conference code: 103418
