We show that regularization of gauge theories by higher covariant derivatives and gauge invariant Pauli-Villars regulators is a consistent method if the Pauli-Villars vector fields are considered in a covariant α–gauge with α 6= 0 and a given auxiliary preregularization is introduced in order to uniquely define the regularization. The limit α → 0 in the regulating Pauli-Villars fields is pathological and the original Slavnov proposal in covariant Landau gauge is not correct because of the… CONTINUE READING
