Conformal invariant regularization in gauge theories
Regularized current propagators and gauge field propagators are expanded over \(\varepsilon\) at space dimension \(D \geq 4\) where \(D\) is even. Here a special regularization (according to scaling) of fields enables to obtain at \(\varepsilon = 0\) limits a well defined conformal theory.
