The neutron anomaly in the gamma N --> eta N cross section through the looking glass of the flavour SU(3) symmetry

T. Boika, V. Kuznetsov, M. V. Polyakov

We study the implications of the flavour SU(3) symmetry for various interpretations of the neutron anomaly in the $\gamma N\to \eta N$ cross section. We show that the explanation of the neutr…
