Phys. Rev. D 53, 967–973 (1996)Chiral symmetry breaking via multifermion Green functionsReceived 23 May 1995; published in the issue dated 15 January 1996 Previous results on fermion chirality-flipping four-point functions are extended to SU(N) gauge theories. The problem is purely nonperturbative, and it is approached by truncating the Schwinger-Dyson hierarchy. The large-N limit also simplifies the problem substantially. The resulting equation is solved numerically by relaxation techniques and an estimate of the critical coupling and momentum behavior is obtained. We also comment on the behavior of chirality-flipping 2n-point functions for general n. © 1996 The American Physical Society. © 1996 The American Physical Society URL:
