Further study of the $e^{+}e^{-} \to f \overline{f}$ process with the aid of CalcPHEP system

In this paper we complete a description of calculation of the one-loop amplitude for e+e- -->f fbar process started in CERN-TH/2001-308. This study is performed within the framework of the project CalcPHEP. Here we add QED subsets of the one-loop diagrams and the soft-photon contribution. The for...

description In this paper we complete a description of calculation of the one-loop amplitude for e+e- -->f fbar process started in CERN-TH/2001-308. This study is performed within the framework of the project CalcPHEP. Here we add QED subsets of the one-loop diagrams and the soft-photon contribution. The formulae we derived are realized in two independent FORTRAN codes,eeffLib, which was written in an old fashioned way, i.e. manually, and another one, created automatically with an aid of s2n_f (symbols to numbers) software -- a part of CalcPHEP system. We present a comprehensive comparison between the two our codes as well as with the results existing in the world literature.
