Description
We show that conventional asymmetric chiral random matrix models (ChRMM), with a gaussian distribution in the asymmetry, provide for a screening of the topological charge and a resolution of the U(1) problem in the unquenched approximation. Our exact results to order 1/N are in agreement with numerical estimates using large ensembles of asymmetric ChRMM with gaussian distributions. (orig.)
