My Mathematica codes:
- partial_waves.m
the partial wave decomposition - dirac.m
The code for the helicity amplitude calculation. It enables the construction of bispinors and the evaluation of 'sandwich' chains of bispinors and other Dirac algebra objects. - fermvrtx.m
MATHEMATICA code for the evaluation of coupling constants of f\bar{f}Z and f\bar{f}V vertices.
