Abstract: (APS)

Chiral-symmetry breaking in (2+1)-dimensional QED is studied in the many-flavor limit. Analytical and numerical solutions of the Dyson-Schwinger equation are found. Substitution of the symmetry-breaking solution in the composite-operator effective potential indicates that it is favored over the symmetric solution. Improvements and possible extensions of the analysis are discussed.
