Chiral symmetry breaking at large image Original Research Article

We present numerical evidence for the hypothesis that, in the planar limit, four-dimensional Euclidean Yang–Mills theory on a finite symmetrical four-torus breaks chiral symmetry spontaneously when the length of the sides l is larger than a critical value image with a bilinear condensate whose value is independent of l. Therefore spontaneous symmetry breaking occurs at finite volume and infinite image reduction holds for the chiral condensate.
