Study of $\eta$ photoproduction on the proton in a chiral constituent quark approach via one-gluon-exchange model

Jun He, B. Saghai, Zhenping Li

A formalism based on a chiral quark model ($\chi$QM) approach complemented with a one-gluon exchange model, to take into account the breakdown of the $SU(6)\otimes O(3)$ symmetry, is…
