WebThe chiral symmetry transformation can be divided into a component that treats the left-handed and the right-handed parts equally, known as vector symmetry, and a component that actually treats them differently, known as axial symmetry. (cf. Current algebra.) A scalar field model encoding chiral symmetry and its breaking is the chiral model. Webwhere is a dimensionless coupling. In differential-geometric language, the field is a section of a principal bundle: with fibres isomorphic to the principal homogeneous space for M (hence why this defines the principal chiral model.
