Abstract

We investigate the universal features of chiral symmetry breaking in large-NN QCD by comparing non-perturbative determinations of the low-lying Dirac spectrum with chiral Random Matrix Theory (RMT) predictions. Our numerical Monte Carlo calculations are based on a chiral lattice discretization of the Dirac operator, and exploit twisted volume reduction to reach NN as large as 841. Matching lattice data with RMT analytic results, we are able to extract the large-NN chiral condensate, which is compared with a recent determination obtained with non-chiral Wilson quarks from twisted volume-reduced models.
