Abstract
The nucleon resonances near 2 GeV are investigated through the (1385) and photoproductions within a Regge-plus-resonance approach based on the new experimental data released by the CLAS Collaboration. The and the are found essential to reproduce the experimental data and should be assigned as second and third in the constituent quark model, respectively. A calculation of the binding energy and decay pattern supports that the , which is listed in the PDG as the third nucleon resonance instead of the , is from the interaction rather than a three quark state.
