✦ Synopsis

We give the renormalization of the standard model of electroweak interactions to all orders of perturbation theory by using the method of algebraic renormalization, which is based on general properties of renormalized perturbation theory and not on a specific regularization scheme. The Green functions of the standard model are uniquely constructed to all orders, if one defines the model by the Slavnov Taylor identity, Ward identities of rigid symmetry, and the specific form of the abelian local gauge Ward identity. Special attention is directed to the mass diagonalization of massless and massive neutral vectors and ghosts. For obtaining offshell infrared finite expressions it is required to take into account higher order corrections into the functional symmetry operators. It is shown that the normalization conditions of the on-shell schemes are in agreement with the most general symmetry transformations allowed by the algebraic constraints.
