摘要:

AbstractWe review the techniques necessary for the calculation of virtual electroweak and soft photonic corrections at the one‐loop level. In particular we describe renormalization, calculation of one‐loop integrals and evaluation of one‐loop Feynman amplitudes. We summarize many explicit results of general relevance. We give the Feynman rules and the explicit form of the counterterms of the electroweak standard model, we list analytical expressions for scalar one‐loop integrals and reduction of tensor integrals, we present the decomposition of the invariant matrix element for processes with two external fermions and we give the analytic form of soft photonic corrections. These techniques are applied to physical processes with externalW‐bosons. We present the full set of analytical formulae and the corresponding numerical results for the decay width of theW‐boson and the top quark. We discuss the cross section for the production ofW‐bosons ine+e−annihilation including allO(x)radiative corrections and finite width effects. Improved Born approximations for these proc
