Charges, parity doublets and parity-non-conservation

Abstract : Charges and Parity-Non-Conservation are two ingredients that, at present, are introduced by hand in the description of particles and their interactions. We elaborate on a suggestion which was made in the past by Landau and tends to relate them. Particles and their antiparticles are associated here to the parity partners appearing in a model with chiral and parity symmetry realized in the Wigner-Weyl mode, i.e. with parity doublets or, equivalently, states of opposite chiral charges. Parity-non-conservation in such a model is ascribed to the non-commutativity of the parity and the (chiral) charge operators, preventing one to have eigenstates of both at the same time
