polarized amplitude or helicity amplitude
Asked by
Zafer ALTIN
Dear Belyaev,
I haven't got much experience in CalcHEP. I'm interested in polarized cross-section for scattering process but I couldn't find any information and samples. I choose Photon, Photon -> X,X
1. For polarization A%, A% -> X,X
I controlled the Mathematica code amplitudes depend on Helicity.
Helicity N1 Helicity N2
is this helicity amplitude?
Left or right handed option or polarized amplitude?
I'm sorry my question is not a good question. I haven't enough theoretical background.
