Cohomology and Renormalization of BFYM Theory in three Dimensions
Alberto Accardi, Andrea Belli, Maurizio Martellini, Mauro Zeni
Abstract
The first order formalism for 3D Yang-Mills theory is considered and two different formulations are introduced, in which the gauge theory appears to be a deformation of the topological BF theory. We perform the quantization and the algebraic analysis of cohomology and renormalization for both the models, which are found to be anomaly free. We discuss also their stability against radiative corrections, giving the full structure of possible counterterms, requiring an involved matricial renormalization of fields and sources.
