Large N QCD -- Continuum reduction

Abstract

Numerical evidence combined with Eguchi-Kawai reduction indicate that there are no finite volumes effects in the large N limit of QCD as long as the linear extent of the four-torus is bigger than a critical size. This is referred to as continuum reduction. Since fermions in the fundamental representation are naturally quenched in the large N limit, as long as we only have a finite number of flavors, continuum reduction provides us with the exciting possibility to numerically solve large N QCD using chiral fermions and present day computers.
