Axial Anomaly through Analytic Regularization
نویسندگان
چکیده
In this work we consider the 2-point Green’s functions in (1+1) dimensional quantum electrodynamics and show that the correct implementation of analytic regularization gives a gauge invariant result for the vacuum polarization amplitude and the correct coefficient for the axial anomaly.

Is the axial anomaly really determined in a continuous non-perturbative regularization?
In the framework of a gauge invariant continuous and non-perturbative regularization scheme based on the smearing of point like interactions by means of cutoff functions, we show that the axial anomaly, though cutoff independent, depends on the shape of the cutoff functions. The standard value for the strength of the axial anomaly is recovered if we assume that the regularized gauge invariant a...
متن کاملExplicit Calculation of the Renormalized Singlet Axial Anomaly
A careful and complete discussion is given of the renormalization of the singlet axial anomaly equation in a vector-like nonabelian gauge theory such as QCD regularized by ordinary dimensional regularization. Pseudotensorial structures are treated with the ’t Hooft-Veltman prescription. A general framework for calculations is developed, and subsequently verified by explicit computations through...

متن کاملTwo-dimensional Chiral Anomaly in Differential Regularization
The two-dimensional chiral anomaly is calculated using differential regularization. It is shown that the anomaly emerges naturally in the vector and axial Ward identities on the same footing as the four-dimensional case. The vector gauge symmetry can be achieved by an appropriate choice of the mass scales without introducing the seagull term. We have analyzed the reason why such a universal res...
متن کاملThe Axial Vector Current Anomaly and the Meson Decay Constants for the Improved Lattice Fermion Action
We discuss the anomaly in the axial vector current for the improved fermion action on the lattice. A detailed discussion of the fermion regularization dependence of the anomaly is given and it is shown that for finite lattice spacing the improved fermion action gives a more reasonable value for the anomaly contribution at finite quark mass than the Wilson action. We also present some results on...
