In spacetime dimensions strictly greater than four, the only consistent interaction terms are those gauge invariant under the original symmetry. Only in four spacetime dimensions the gauge symmetry is found deformed.24 pages; two equations corrected; matches the published versionHigh Energy Physics - Theorytext
