Zero Temperature Chiral Phase Transition in SU(N) Gauge Theories.
We investigate the zero temperature chiral phase transition in an SU(N) gauge theory as the number of fermions Nf is varied. We argue that there exists a critical number of fermions N c f , above which there is no chiral symmetry breaking or confinement, and below which both chiral symmetry breaking and confinement set in. We estimate N c f and discuss the nature of the phase transition. An SU(...
متن کاملA Comment on the Zero Temperature Chiral Phase Transition in SU(N) Gauge Theories
Recently Appelquist, Terning, andWijewardhana investigated the zero temperature chiral phase transition in SU(N) gauge theory as the number of fermions Nf is varied. They argued that there is a critical number of fermions N c f , above which there is no chiral symmetry breaking and below which chiral symmetry breaking and confinement set in. They further argued that that the transition is not s...

متن کاملZero Temperature Chiral Phase Transition in (2+1)-Dimensional QED with a Chern-Simons Term
We investigate the zero temperature chiral phase transition in (2+1)dimensional QED in the presence of a Chern-Simons term, changing the number of fermion flavors. In the symmetric phase, there are no light degrees of freedom even at the critical point. Unlike the case without a Chern-Simons term, the phase transition is first-order. 11.10.Kk, 12.20.Ds, 11.15.Tk Typeset using REVTEX Email addre...
متن کاملChiral Phase Transition for SU(N) Gauge Theories
We describe [1] the chiral phase transition for vector-like SU(N) gauge theories as a function of the number of quark flavors Nf by making use of an anomalyinduced effective potential. The potential depends explicitly on the full β-function and the anomalous dimension γ of the quark mass operator. By using this potential we argue that chiral symmetry is restored for γ < 1. A perturbative comput...
