Therefore special efforts have to be made to define a gauge theory with a local chiral symmetry. That anomalous gauge theories can be made sense of in two dimensions was shown many years ago .

A lattice non-perturbative definition of an SO(10) chiral gauge theory ...

WebWith this duality constraint imposed, one speaks of self-dual higher gauge fields or chiral higher gauge fields or higher gauge fields with self-dual curvature. (These are a higher degree/dimensional generalization of what in Yang-Mills theory are called Yang-Mills instanton field configurations.). Since imposing the self-duality constraint on the fields … WebNov 1, 2004 · We extend the construction of lattice chiral gauge theories based on non-perturbative gauge fixing to the non-Abelian case. A key ingredient is that fermion doublers can be avoided at a novel type of critical point which is only accessible through gauge fixing, as we have shown before in the Abelian case. sons of the forest find team

SU (N) chiral gauge theories on the lattice - OSTI.GOV

WebOct 1, 1989 · We explain the difficulties encountered in the application of these techniques to the definition of the effective action for chiral gauge theories, and in particular the quantum mechanical breakdown of chiral gauge invariance leading to chiral anomalies, the structure of which is reviewed in detail. Web6. Gauge-invariant lattice regularization of anomaly-free theories 1. Introduction A characteristic feature of the electroweak interactions is that the left- and right-handed components of the fermion fields do not couple to the gauge fields in the same way. The term chiral gauge theory is reserved for field theories of this type, while sons of the forest fishing traps
