Chiral gauge theory
WebJun 23, 1998 · Chiral gauge theory is so central to our understanding of the electroweak interactions and yet is susceptible to the anomalous violation of the very gauge symmetry defining the theory and,... WebJan 18, 1999 · Luscher's recent formulation of Abelian chiral gauge theories on the lattice, in the vacuum (or perturbative)sector in infinite volume, is reinterpreted in terms of the lattice covariant regularization. The gauge invariance of the effective action and the integrability of the gauge current in anomaly-free cases become transparent.

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 WebMay 5, 2013 · The standard model is a chiral gauge theory where the gauge fields couple to the right-hand and the left-hand fermions differently. The standard model is defined perturbatively and describes all elementary particles (except gravitons) very well.

WebAug 25, 1997 · We construct brane configurations leading to chiral four dimensional N=1 supersymmetric gauge theories. The brane realizations consist of intersecting Neveu-Schwarz five-branes and Dirichlet four-branes in non-flat spacetime backgrounds. We discuss in some detail the construction in a C^2/Z_M orbifold background.
WebThen classically the axial vector current jµ5 has the same expression as the gauge current jµ in chiral theory.
