Abstract
Within a multi-channels multi-resonances reaction model of pion nucleon reactions, we examine the properties of the nucleon resonances with masses less than 2 GeV. The Roper resonance and the second resonance in P 11 are found to evolve dynamically from the same bare state. With the exception of the P 13 and P 31 resonances, our resonance pole positions agree well with the 3 and 4 star resonances listed by the Particle Data Group.
