$e^{+}{e}^{-}$ into 4 fermions + ${\hat{I}}^3$ with ALPHA

Abstract

We apply the iterative numerical algorithm ALPHA, which automatically generates the N-point Green functions (as recently suggested \cite{alpha}) to the computation of the production rate of four fermions and four fermions plus photon in electron-positron annihilation. The discussion of the physical results is preceded by an introduction on the algorithm.
