Gauge Anomalies in an Effective Field Theory*
نویسنده
چکیده
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 qualitatively different character in Abelian and non-Abelian anomalous gauge theories. cl 1991 Academic Press. Inc.

Hawking radiation from rotating black holes in anti-de Sitter spaces via gauge and gravitational anomalies
Robinson-Wilczek’s recent work, which treats Hawking radiation as a compensating flux to cancel gravitational anomaly at the horizon of a Schwarzschild-type black hole, is extended to study Hawking radiation of rotating black holes in anti-de Sitter spaces, especially that in dragging coordinate system, via gauge and gravitational anomalies. The results show that in order to restore gauge invar...
متن کاملPlanar and Nonplanar Konishi Anomalies and Exact Wilsonian Effective Superpotential for Noncommutative N = 1 Supersymmetric U ( 1 )
Abstract The Konishi anomalies for noncommutative N = 1 supersymmetric U(1) gauge theory arising from planar and nonplanar diagrams are calculated. Whereas planar Konishi anomaly is the expected ⋆-deformation of the commutative anomaly, nonplanar anomaly reflects the important features of nonplanar diagrams of noncommutative gauge theories, such as UV/IR mixing and the appearance of nonlocal op...
متن کاملField Dependent Gauge Couplings in Locally Supersymmetric Effective Quantum Field Theories ⋆
We investigate the field dependence of the gauge couplings of locally supersymmetric effective quantum field theories. We find that the Weyl rescaling of supergravity gives rise to Wess-Zumino terms that affect the gauge couplings at the one-loop level. These Wess-Zumino terms are crucial in assuring supersymmetric consistency of both perturbative and non-perturbative gauge interactions. At the...
متن کاملOn Anomalies in Orbifold Theories
We study the issue of gauge invariance in five-dimensional theories compactified on an orbifold S/(Z2×Z2) in the presence of an external U(1) gauge field. From the fourdimensional point of view the theory contains a tower of Kaluza-Klein Dirac fermions with chiral couplings and it looks anomalous at the quantum level. We show that this “anomaly” is cancelled by a topological Chern-Simons term w...
متن کاملThe Axial Anomaly Revisited *
We consider theories with gauged chiral fermions in which there are abelian anomalies, and no nonabelian anomalies (but there may be nonabelian gauge fields present). We construct an associated theory that is gauge-invariant, renormalizable, and with the same particle content, by adding a finite number of terms to the action. Alternatively one can view the new theory as arising from the origina...
