Dynamical resolution of the U(1) problem in QCD
Description
The nonperturbative and perturbative aspects of the U(1) problem are discussed and linked to the dynamical breakdown of chiral symmetry in QCD. Then a U(1) gap equation is obtained and is approximately saturated with two-gluon intermediate states corresponding to the U(1) anomaly and consistent with eta-eta' mixing. (orig.)
