Abstract

The coupled-channel unitary Lagrangian (Giessen) model is extended to study two pion production within the isobar approximation. The effect from the t-channel pion exchange to the πN → σN reaction is found to be small which is in line with the previous conclusions by the Crystal Ball collaboration. The calculations with the genuine Roper resonance are found to be in nice agreement with both the Crystal Ball measurements of the 2πN production and the GWU single energy solutions in the elastic πN channel.
