Inconsistencies of the U(1) theory of electrodynamics: Stress energy momentum tensor

The internal gauge space of electrodynamics considered as a U(1) gauge fiel d theory is a scalar. This leads to the result that in free space, and for plane waves, the Poynting vector and energy vanish. This result is consiste nt with the fact that U(1) gauge field theory results in a null third Stoke s parameter, meaning again that the field energy vanishes in free space. A self consistent definition of the stress energy momentum tensor is obtained with a Yang Mills theory applied with an O(3) symmetry internal gauge spac e. This theory produces the third Stokes parameter self consistently in ter ms of the self-dual Evans-Vigier fields B(3).
