Parity invariant lattice regularization of three - dimensional gauge - fermion system
In three dimensions, the effective action for the gauge field induced by integrating out a massless Dirac fermion is known to give either a parity-invariant or a parity-violating result, depending on the regularization scheme. We construct a lattice formulation of the massless Dirac fermion using the overlap formalism. We show that the result is parity invariant in contrast to the formulation u...
متن کاملGauge Invariant Pauli–Villars Regularization for Chiral Fermion
We re-examine the generalized Pauli–Villars regularization proposed by Frolov and Slavnov, a possible gauge invariant Lagrangian-level regularization for a chiral fermion. When a chiral fermion belongs to a (pseudo-)real representation of the gauge group, the formulation always provides a complete gauge invariant regularization; a chiral fermion in an anomaly free complex representation seems t...
متن کاملFour-dimensional lattice chiral gauge theories with anomalous fermion content
In continuum field theory, it has been discussed that chiral gauge theories with Weyl fermions in anomalous gauge representations (anomalous gauge theories) can consistently be quantized, provided that some of gauge bosons are permitted to acquire mass. Such theories in four dimensions are inevitablly non-renormalizable and must be regarded as a low-energy effective theory with a finite ultravi...
متن کاملInvariant Regularization of Supersymmetric Chiral Gauge Theory
We formulate a manifestly supersymmetric gauge covariant regularization of supersymmetric chiral gauge theories. In our scheme, the effective action in the superfield background field method above one-loop is always supersymmetric and gauge invariant. The gauge anomaly has a covariant form and can emerge only in one-loop diagrams with all the external lines being the background gauge superfield...
متن کاملGauge-Invariant Noncompact Lattice Simulations
Three techniques for performing gauge-invariant, noncompact lattice simulations of nonabelian gauge theories are discussed. In the first method, the action is not itself gauge invariant, but a kind of lattice gauge invariance is restored by random compact gauge transformations during the successive sweeps of the simulation. This method has been applied to pure SU(2) gauge theory on a 12 lattice...
