More about the axial anomaly on the lattice
Hiroshi Igarashi, Kiyoshi Okuyama, Hiroshi Suzuki
We study the axial anomaly defined on a finite-size lattice by using a Dirac operator which obeys the Ginsparg-Wilson relation. When the gauge group is U(1), we show that the basic…
Errata and Addenda to ``Anomaly Cancellation Condition in Lattice Gauge Theory''
Hiroshi Igarashi, Kiyoshi Okuyama, Hiroshi Suzuki
We correct some intermediate expressions and arguments in hep-lat/0002009 (Nucl. Phys. B 585 (2000) 471--513). The main results do not change. We also mention some additional obser…
Invariant Regularization of Supersymmetric Chiral Gauge Theory
Hiroshi Suzuki
We present a regularization scheme which respects the supersymmetry and the maximal background gauge covariance in supersymmetric chiral gauge theories. When the anomaly cancellati…
Remark on the Consistent Gauge Anomaly in Supersymmetric Theories
Yoshihisa Ohshima, Kiyoshi Okuyama, Hiroshi Suzuki +1
We present a direct field theoretical calculation of the consistent gauge anomaly in the superfield formalism, on the basis of a definition of the effective action through the cova…
Invariant Regularization of Supersymmetric Chiral Gauge Theory. II
Takuya Hayashi, Yoshihisa Ohshima, Kiyoshi Okuyama +1
By undertaking additional analyses postponed in a previous paper, we complete our construction of a manifestly supersymmetric gauge-covariant regularization of supersymmetric chira…
Invariant Regularization of Supersymmetric Chiral Gauge Theory
Takuya Hayashi, Yoshihisa Ohshima, Kiyoshi Okuyama +1
We formulate a manifestly supersymmetric gauge covariant regularization of supersymmetric chiral gauge theories. In our scheme, the effective action in the superfield background fi…
Manifestly Gauge Covariant Treatment of Lattice Chiral Fermions. II
Kiyoshi Okuyama, Hiroshi Suzuki
We propose a new formulation of chiral fermions on a lattice, on the basis of a lattice extension of the covariant regularization scheme in continuum field theory. The species doub…
Remark on Pauli-Villars Lagrangian on the Lattice
Kazunobu Haga, Hiroshi Igarashi, Kiyoshi Okuyama +1
It is interesting to superimpose the Pauli-Villars regularization on the lattice regularization. We illustrate how this scheme works by evaluating the axial anomaly in a simple lat…
Path Integral Evaluation of Non-Abelian Anomaly and Pauli--Villars--Gupta Regularization
Kiyoshi Okuyama, Hiroshi Suzuki
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, app…
Gauge Invariant Pauli-Villars Regularization of Chiral Fermions
Kiyoshi Okuyama, Hiroshi Suzuki
We extend the idea of the generalized Pauli-Villars regularization of Frolov and Slavnov and analyze the general structure of the regularization scheme. The gauge anomaly-free cond…
