Numerical calculation of Feynman amplitudes for electroweak theories and an application to e+e−→W+W−γ

Abstract
The method for the numerical calculation of Feynman amplitudes developed in a previous paper is extended to the standard electroweak theory (Weinberg-Salam model). All possible types of vertices contained in this model are added in the program package. As an application, the tree-level cross section for the process e

Nature of problem
Measurements of higher order effects of electroweak interactions at high energies give crucial tests of Standard Model in elementary particle physics. In electroweak theories, various types of interactions contribute so that calculations of these effects become quite complicated in the framework of the traditional technique based on algebraic manipulation. It is therefore desirable to construct more efficient algorithms to calculate cross sections for complicated and numerous sets of Feynman dia ...
