Abstract

Chirality as a symmetry of particle physics occupies a unique role in the standard model. It arises from general space-time principles yet remains central to the formulation of local gauge theories. This work explores the complexities arising from a physically comprehensive treatment of this topic. We present the origins of the property from first principles by deriving the chiral Dirac equation (CDE). We demonstrate how the resulting chiral degrees of freedom for spin-1/2 objects may be employed in constructing composite chiral objects through the Bargmann-Wigner formalism, leading to novel couplings. We then consider means by which the degrees of chiral freedom in the standard model may be spontaneously broken through left-chiral Majorana neutrino fields. The resulting modifications to standard model processes are explored before a final exploration of chirality in curved space-time.
