Title: Dynamical components in the N(1535) from photoproduction

Keywords: Dynamically generated resonances

Abstract:

The concept dynamical generation of the N(1535) has been tested for a wide range of different reactions. We perform a global fit of photon- and pion-induced reactions with piN, etaN and KY final states. Resonance interference with the N^*(1650) turns out to be an important ingredient which has been overlooked many times in the past.

We also show the sensitivity on the phase in pion photoproduction which can help clearly distinguish between genuine and dynamically generated states.
