Abstract

The nature of some baryonic resonances is still an unresolved issue. The case of the N *(1535) is particularly interesting in this respect due to the nearby \( \eta\) N threshold and interference with the N *(1650) . The N *(1535) has been described as a threshold effect, as a genuine 3-quark resonance, or as dynamically generated from the interaction of the octet of baryons with the octet of mesons. In the scheme of dynamical generation, predictions for the interaction of the N *(1535) with the photon can be made. In this study, we simultaneously analyze the role of the N *(1535) in the \( \pi\) N \( \rightarrow\) \( \pi\) N and \( \gamma\) N \( \rightarrow\) \( \pi\) N reactions and compare to the respective amplitudes from partial-wave analyses. This test is very sensitive to the meson-baryon components of the N *(1535) .
