Gauge Anomalies in an Effective Field Theory*

A four-dimensional gauge theory with anomalous fermion content can be consistently quantized, provided that at least some gauge fields are permitted to have nonvanishing masses. Such a theory is nonrenormalizable; there is a maximal value of the ultraviolet cutoff ,4. beyond which the locality of the theory breaks down. The maximal ,4 can be estimated in perturbation theory and has a qualitativ...

Effective Field Theory and Matching in Non-Relativistic Gauge Theories

The effective Lagrangian and power counting rules for non-relativistic gauge theories are derived via a systematic expansion in the large c limit. It is shown that the 1/c expansion leads to an effective field theory which incorporates a multipole expansion. Within this theory there is no need for heuristic arguments to determine the scalings of operators. After eliminating c from the lowest or...

Effective theory for real-time dynamics in hot gauge theories

For a high temperature non-Abelian plasma, we reformulate the hard thermal loop approximation as an effective classical thermal field theory for the soft modes. The effective theory is written in local Hamiltonian form, and the thermal partition function is explicitly constructed. It involves an ultraviolet cutoff which separates between hard and soft degrees of freedom in a gauge-invariant way...

Renormalizable Abelian-projected effective gauge theory derived from Quantum Chromodynamics

Abstract We show that an effective Abelian gauge theory can be obtained as a renormalizable theory from QCD in the maximal Abelian gauge. The derivation improves the previous version which was obtained by one of the authors and was called the Abelianprojected effective gauge theory. This result supports a view that we can construct an effective Abelian gauge theory from QCD without losing chara...

Gauge Invariant Effective Action in Abelian Chiral Gauge Theory on the Lattice

Lüscher’s recent formulation of Abelian chiral gauge theories on the lattice, in the vacuum (or perturbative) sector in infinite volume, is reinterpreted in terms of the lattice covariant regularization. The gauge invariance of the effective action and the integrability of the gauge current in anomaly-free cases become transparent. The real part of the effective action is simply one-half that o...
