HIGHER COVARIANT DERIVATIVE REGULATORS AND NON-MULTIPLICATIVE RENORMALIZATION

The renormalization algorithm based on regularization methods with two regulators is analyzed by means of explicit computations. We show in particular that regularization by higher covariant derivative terms ca n be complemented with dimensional regularization to obtain a consiste nt renormalized 4-dimensional Yang-Mills theory at the one-loop level. This shows that hybrid regularization methods can be applied not only to finite theories, like e.g. Chem-Simons, but also to divergent theo ries.
