Topologically massive chromodynamics in the perturbative regime

Topologically massive SU(N) gauge theories are studied by using the loop expansion in the Landau gauge. Ward identities for infinitesimal and topologically nontrivial gauge transformations are derived, and checked to one-loop order.

Zusammenfassung:Topologically massive SU(N) gauge theories are studied by using the loop expansion in the Landau gauge. Ward identities for infinitesimal and topologically nontrivial gauge transformations are derived, and checked to one-loop order. The renormalized propagators and vertices are shown to be well behaved about zero momentum to arbitrary order in perturbation theory. We also establish that only massive states contribute to the discontinuities of physical amplitudes.
