Chiral Bargmann-Wigner Equations for Spin-1 Massive Fields

Abstract

The Bargman-Wigner equations are generalized to include chiral symmetry based on the irreps of the Poincaré group, and the chirial Bargmann-Wigner equations are derived for spin-1 massive fields. By specifying the chiral basis, the chiral Bargmann-Wigner equations are reduced to the Proca-like equation, which is coupled by chirality to an auxiliary equation for spin-0 massive field. The coupling is a new phenomenon whose physical implications for the Higgs field and dark matter are discussed.
