Gluons in the ${\eta }^{\mathrm{\prime }}$ and in nucleon resonances

We discuss the role of gluon dynamics in ${\eta }^{\mathrm{\prime }}$ physics and in nucleon resonances where excitations of gluonic potentials may also be important. Interesting phenomenology includes a possible narrow near threshold resonance in ${\eta }^{\mathrm{\prime }}$ photoproduction and whether the parity doublets observed in the higher mass nucleon resonance spectrum might be hinting at a possible second minimum in the confinement potential corresponding to supercritical confinement.
