A revised and complete list of the electroweak chiral Lagrangian operators up to dimension four is provided. The connection of these operators to the [ital S], [ital T], and [ital U] parameters andExpand

Critical behavior in (2+1)-dimensional QCD.
QCD in 2+1 dimensions with {ital N} species of fermions, analyzed in the 1/{ital N} expansion, is shown to exhibit a chiral and confinement phase transition as {ital N} approaches a critical valueExpand

Spontaneous chiral-symmetry breaking in three-dimensional QED.
A detailed analysis is given of chiral-symmetry breaking in the large-flavor (N) limit of quantum electrodynamics in (2+1) dimensions. Analytical and numerical solutions of the homogeneousExpand

Zero Temperature Chiral Phase Transition in SU(N) Gauge Theories.
We investigate the zero temperature chiral phase transition in an SU({ital N}) gauge theory as the number of fermions {ital N}{sub {ital f}} is varied. We argue that there exists a critical number ofExpand

Unitarity bound on the scale of fermion mass generation.
Partial-wave unitarity implies an upper limit on the energy scale of the mechanism that generates quark and lepton masses.

Chiral hierarchies and flavor-changing neutral currents in hypercolor.
Dynamical chiral-symmetry breaking in asymptotically free theories with a slowly running coupling is analyzed. When the confinement scale ..lambda.. is much less than the cutoff M beyond which theExpand

Ladder approximation for spontaneous chiral-symmetry breaking.
This paper examines the validity of the ladder approximation in gauge theories such as technicolor theories in which the coupling is a slowly running function of momentum and is large enough toExpand

Breaking of isospin symmetry in theories with a dynamical Higgs mechanism.
The sensitivity of physical amplitudes to the observed isospin-symmetry breaking in the fermion mass matrix is analyzed in theories where the electroweak symmetry is dynamically broken. As a firstExpand

(2+1)-dimensional QED and a novel phase transition.
We investigate the chiral phase transition in (2+1)-dimensional QED. Previous studies of symmetry breaking have found that symmetry breaking ceases to occur when the number of fermion flavors exceedsExpand
