Gluons in the η' and in nucleon resonances
Abstract
We discuss the role of gluon dynamics in η' physics and in nucleon resonances where excitations of gluonic potentials may also be important. Interesting phenomenology includes a possible narrow near threshold resonance in η' 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.
