The U(1) Problem in Chiral Random Matrix Models
arXiv:hep-lat/9611012 · doi:10.1016/S0550-3213(97)00265-4
Abstract
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 problem in the unquenched approximation. Our exact results to order are in agreement with numerical estimates using large ensembles of asymmetric ChRMM with gaussian distributions.
