Description
Chiral symmetry is studied in the strong coupling limit of lattice gauge theory with staggered fermions. It is shown rigorously that chiral symmetry is broken spontaneously in QED and the gauge-invariant Nambu-Jona-Lasinio model if the dimension of spacetime is at least four. The results for the chiral condensate as a function of the mass imply that the mean-field approximation is an upper bound for this observable which becomes exact as the dimension goes to infinity. For this model with gauge group U(N), N=2,3,4, chiral long-range order is proven to exist at zero mass in four or more dimensions
