Two-dimensional Chiral Anomaly in Differential Regularization
نویسنده
چکیده
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 result can be obtained in differential regularization. PACS: 11.10.Kk ; 11.15.-q

General treatment of anomalies in ( 1 , 0 ) and ( 1 , 1 ) two - dimensional super - gravity
In this paper we discuss the interplay among (super-)coordinate, Weyl and Lorentz anomaly both in chiral and non-chiral super-gravity represented by (1, 0) and (1, 1) two-dimensional models. It is shown that for this purpose two regu-larization dependent parameters are needed in the effective action. We discuss in full generality the regularization ambiguities of the induced effective action an...
متن کاملA Note on “Anomalous” Chiral Gauge Theories
We show that, the lattice regularization of chiral gauge theories proposed by Kaplan, when applied to a (2+1)-dimensional domain wall, produces a (1+1)-dimensional theory at low energy even if gauge anomaly produced by chiral fermions does not cancel. But the corresponding statement is not true in higher dimensions. Chiral gauge theories deserve deeper study because nature exhibits left-right a...
متن کاملPath Integral Evaluation of Non-Abelian Anomaly and Pauli–Villars–Gupta Regularization
When the path integral method of anomaly evaluation is applied to chiral gauge theories, two different types of gauge anomaly, i.e., the consistent form and the covariant form, appear depending on the regularization scheme for the Jacobian factor. We clarify the relation between the regularization scheme and the Pauli–Villars–Gupta (PVG) type Lagrangian level regularization. The conventional PV...
متن کاملLarge mass limit of the continuum theories in Kaplan's formulation.
Being inspired by Kaplan’s proposal for simulating chiral fermions on a lattice, we examine the continuum analog of his domain-wall construction for two-dimensional chiral Schwinger models. Adopting slightly unusual dimensional regularization, we explicitly evaluate the one-loop effective action in the limit that the domain-wall mass goes to infinity. For anomaly-free cases, the effective actio...
متن کاملOverlap for 2D chiral U(1) models
Two dimensional chiral gauge theories provide a convenient testing ground for non-perturbative regularizations since they are much simpler to simulate numerically than four dimensional ones. As in four dimensions, there are anomalies in two dimensions that have to be cancelled and anomaly free theories can have global charges that are broken by topologically non-trivial gauge fields. In this ta...
