Critical couplings for chiral symmetry breaking via instantons
Using an instanton effective action formalism, we compute the critical coupling for the nonperturbative formation of a dynamical mass via instantons in non-Abelian gauge theories with N_f massless fermions. Only continuous phase transitions are considered. For large values of N_f the critical coupli...

Abstract | Using an instanton effective action formalism, we compute the critical
coupling for the nonperturbative formation of a dynamical mass via instantons
in non-Abelian gauge theories with N_f massless fermions. Only continuous phase
transitions are considered. For large values of N_f the critical couplings are
found to be much smaller than the equivalent critical couplings obtained from
gauge exchange calculations in the ladder approximation. |
