WebFeb 14, 2024 · The U.S. Department of Energy's Office of Scientific and Technical Information WebSep 19, 2011 · The term "chiral model" is then used to describe effective scalar or scalar-vector theories of mesons, which describe the effective oscillations of the chiral condensate. It has been extended to describe many different nonlinear sigma models which resemble the original Gell-Mann Levy sigma model.

The gauge invariance of the effective action and the integrability of the gauge current in anomaly-free cases become transparent.
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.
