In this subsection we review the role of the Higgs boson in preserving
unitarity of the scattering amplitudes in the Standard Model
(SM). We will look at the processes
,
and
for longitudinally polarized
gauge bosons. Special emphasis will be put in using algebraic methods
(package FeynCalc for mathematica) to evaluate the
amplitudes and cross sections. A discussion, in the form of an
article, can be found here.
The calculations were done using the following programs for FeynCalc:
