WebNov 21, 2011 · In continuum field theory, it has been discussed that chiral gauge theories with Weyl fermions in anomalous gauge representations, the so-called anomalous gauge theories [1,2,3,4,5,6,7,8, 10, 11 ... WebWe will refer to a gauge theory with fermions transforming as a complex representation of the gauge group as a chiral gauge theory, because the gauged symmetry is a chiral symmetry, rather than a vector-like symmetry (such as QCD). But my question is: why does a Complex Representation of gauge group imply a Chiral Gauge Theory? how does math relate to music

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. WebSummary: Gauge theory is any field theory in physics in which some global, continuous symmetry of the theory is promoted to a local symmetry. By doing so, a new field is introduced (the gauge field) which has its own dynamics and couples to the particles/fields which have the symmetry.
