OSTI ID:5833660
The author examines the validity of ladder approximation in gauge theories such as technicolor theories in which the gauge coupling is a slowly running function of momentum and is large enough to trigger spontaneous chiral symmetry breaking. He finds that the next-higher-order terms beyond the ladder approximation amount to only a (1-20)% correction, depending on the fermion representation. This indicates that the ladder approximation to spontaneous chiral symmetry breaking is a much better approximation than previously thought.
