Description
The traditional method to compute the square of transition amplitudes involving spin 1/2 particles is particularly difficult to use for spin polarized amplitudes. We present here an alterative method to calculate directly the Feynman amplitude through trace evaluation. This method is not constrained to a special type of polarization or particle mass.
