Ja n 19 96 U A ( 1 ) symmetry restoration in QCD with N f flavors
نویسندگان
چکیده
Recently, there have been reports that the chirally restored phase of QCD is effectively symmetric under U (N f)×U (N f) rather than SU (N f)×SU (N f). We supplement their argument by including the contributions from topologi-cally nontrivial gauge field configurations and discuss how the conclusions are modified. General statements are made concerning the particle spectrum of QCD with light N f flavors in the high temperature chirally restored phase.

The four-fermi model with continuous chiral symmetry is studied in three di-mensions at non-zero chemical potential μ using both the 1/Nf expansion andcomputer simulations. For strong coupling this model spontaneously breaksits U(1) chiral symmetry at zero chemical potential and the Goldstone mech-anism is realized through massless pions. The computer simulation predicts acr...
متن کاملThe Hopf Skyrmion in QCD with Adjoint Quarks
We consider a modification of QCD in which conventional fundamental quarks are replaced by Weyl fermions in the adjoint representation of the color SU(N). In the case of two flavors the low-energy chiral Lagrangian is that of the Skyrme–Faddeev model. The latter supports topologically stable solitons with mass scaling as N. Topological stability is due to the existence of a nontrivial Hopf inva...
متن کاملChiral and U(1) axial symmetry restoration in linear sigma models with two quark flavors
We study the restoration of chiral symmetry in linear sigma models with two quark flavors. The models taken into consideration have a U(2) × U(2) and an O(N) internal symmetry. The physical mesons of these models are σ, pion, η and a0 where the latter two are not present in the O(N) model. Including two-loop contributions through sunset graphs we calculate the temperature behavior of the order ...

We have investigated QED corrections to chiral symmetry breaking in Numbu–Jona-Lasinio (NJL) model with two flavors of quarks. In the model the isospin symmetry is broken by the difference of the current quark mass and the electromagnetic charge between up and down quarks. In the leading order of the 1/N expansion we calculate the effective potential of the model with one-loop QED corrections a...
متن کاملFlavor Doubling and the Nature of Asymptopia
We consider the possibility that QCD with N flavors has a useful lowenergy description with 2N flavors. Specifically, we investigate a free theory of 2N quarks. Although the free theory is U(N)L × U(N)R invariant, it admits a larger U(2N) invariance. However, when the axial anomaly is accounted for in the effective theory by a ’t Hooft interaction, only SU(N)L×SU(N)R×U(1)B ⊂ U(2N) survives. The...
