THE STANDARD MODEL IN THE ON-SHELL SCHEME

We outline the renormalization of the standard model to all orders of perturbation theory in a way which does not make essential use of a sp ecific subtraction scheme but is based on the Slavnov-Taylor identity. Physical fields and parameters are used throughout the paper. The War d-identity for the global gauge invariance of the vertex functions is formulated. As an application the Callan-Symanzik equation is derived.
