Another Example: $e^- e^- \rightarrow W^- e^- \nu_e$

In this subsection, in order to be more precise, we review the techniques used in Quantum Field Theory in a non trivial example, the W-strahlung at a linear collider through the process $e^- e^+ \rightarrow W^- e^- \nu_e$ and related processes. The emphasis is in the use of the package FeynCalc for mathematica. The discussion can be found here. The corresponding programs are

• $e^- e^- \rightarrow W^- e^- \nu_e$
  Mathematica program eeWene.m
  Fortran program eeWene.f
  

• $e^- e^+ \rightarrow W^- e^+ \nu_e$
  Mathematica program eEWEne.m
  Fortran program eEWEne.f
  

• $e^- e^+ \rightarrow W^+ e^- \overline{\nu}_e$
  Mathematica program eEWpeNe.m
  Fortran program eEWpeNe.f
