Critical behavior in (2+1)-dimensional QCD.
- Appelquist, Nash
- Physics, Medicine
- Physical review letters
- 20 June 1988
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 value… Expand
Spontaneous chiral-symmetry breaking in three-dimensional QED.
- Appelquist, Bowick, Karabali, Wijewardhana
- Physics, Medicine
- Physical review. D, Particles and fields
- 15 June 1986
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 homogeneous… Expand
Zero Temperature Chiral Phase Transition in SU(N) Gauge Theories.
- Appelquist, Terning, Wijewardhana
- Physics, Medicine
- Physical review letters
- 23 February 1996
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 of… Expand
Unitarity bound on the scale of fermion mass generation.
- Appelquist, Chanowitz
- Physics, Medicine
- Physical review letters
- 23 November 1987
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.
- Appelquist, Karabali, Wijewardhana
- Physics, Medicine
- Physical review letters
- 25 August 1986
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 the… Expand
Ladder approximation for spontaneous chiral-symmetry breaking.
- Appelquist, Lane, Mahanta
- Physics, Medicine
- Physical review letters
- 3 October 1988
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 to… Expand
Breaking of isospin symmetry in theories with a dynamical Higgs mechanism.
- Appelquist, Bowick, Cohler, Hauser
- Physics, Medicine
- Physical review. D, Particles and fields
- 1 April 1985
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 first… Expand
(2+1)-dimensional QED and a novel phase transition.
- Appelquist, Terning, Wijewardhana
- Physics, Medicine
- Physical review letters
- 18 February 1994
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 exceeds… Expand
