Dear FeynCalc developers,
first of all, thanks for the excellent job.
I was trying to calculate a tree level process with a specific
polarisation vector for some incoming photons. Google pointed me to an
old paper, http://arxiv.org/abs/hep-ph/9710265, where they quote the
function SpecificPolarization[..] which apparently is not there
anymore.
In substance, is there a way to specify a polarisation vector so that a
polarized amplitude can be calculated simply by contracting this
specific vector with the remaining part of the latter?
Thank you for your help,
LK
