Universal features of chiral symmetry breaking in large-N QCD
A bstract We investigate the universal features of chiral symmetry breaking in large- N 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 N as large as 841. Matching lattice data with RMT analytic results, we are able to extract the large- N chiral condensate, which is compared with a recent determination obtained with non-chiral Wilson quarks from twisted volume-reduced models.
