Parity violation and the nature of charges
Abstract.The origin of parity violation in physics is still unknown. At present it is introduced in the theory by requiring that the SU(2) subgroup entering the description of interactions involves the left-handed components. In the present contribution, one elaborates on a suggestion made by Landau that particles and antiparticles could be like “stereo-isomeric” molecules, which would naturally provide parity violation. Particles and antiparticles could thus be combinations of the parity doublets associated with a chiral symmetry realized in the Wigner-Weyl mode. Consequences of such a description and the possible problems it could raise are examined.
