Abstract

Significant isospin effects are observed by the HADES collaboration in inclusive dilepton production channels in the pp and quasi free np experiments at 1.25 GeV kinetic beam energy. Triggered by this observation, analyses of several exclusive channels within either dilepton or pion production have been started to shed more light on the possible explanations. Furthermore, the exclusive π⁺π^- production in np and pp collisions provide tests for a consistent description of double pion production in different isospin states, which is necessary to understand contributions of double δ(1232) and N*(1440) production. This is also important in the context of the recent results from the WASA collaboration on the ABC effect with reference to a d* dibaryon resonance in the isospin 0 channel.
