abstract
The recent precise experimental results for the photoproduction of $\eta$-mesons off the neutron measured with the Crystal Ball/TAPS calorimeter at the MAMI accelerator have been investigated in detail in the framework of the Bonn-Gatchina coupled channel model. The main result is that the narrow structure observed in the excitation function of $\gamma n \rightarrow n\eta$ can be reproduced fully with a particular interference pattern in the $J^P=1/2^-$ partial wave. Introduction of the narrow resonance $N(1685)$ with the properties reported in earlier publications deteriorates the quality of the fit.

Pentaquarks and Maxim V. Polyakov
A review argues that Diakonov-Petrov-Polyakov's narrow-width Theta+ pentaquark prediction remains viable, identifying N*(1685) as the antidecuplet partner and citing LEPS/DIANA data as support.
