Hello Forum: My problem is that I need to use FourDivergence on quantities between Dirac spinors. For example, if I were analytically differentiating, I would find
.GS[w].SpinorU[p1,m], FV[w, a]]=
However, when doing this operation in FeynCalc, only the first of these terms arises----there is no differentiation inside the Dirac spinor piece. Is there a way around this? Thanks.
