WebMay 1, 2024 · Gauge field equations of motion require the current to be conserved, but the anomaly means that the relevant current is not conserved. 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 . Studies … WebThen classically the axial vector current jµ5 has the same expression as the gauge current jµ in chiral theory. The trace anomaly for a left-handed Weyl fermion has been studied by the BMHV prescription in works [22, 28]. There are some problems in BMHV prescription to deal with the chiral ﬁelds [40]. shutter dogs and hinges

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.
