Yes. ComplexConjugate is basically broken. See the comments in ComplexConjugate.m I could try to fix it, but then Phi will have trouble. However, it is probably not at all easy to do this right.
So, if someone has a few days or weeks time: feel free to send me an improved version (with test cases).
>2. Expressions such as
>Eps[Momentum[p1], Momentum[p2], Momentum[p3], Momentum[p4 + p5]]
>do not simplify. I am using it with Mathematica 8
You could either explicitly use MomentumExpand first, or change
ExpandSclalarProduct to MomentumExpand in HighEnergyPhysics/fctools/EpsEvaluate.m
Then also the Calc function will do.
-- Feel free to send more (as concrete as possible) problems or bugs. If it is easy I will fix it right away. If it takes longer, I am afraid I have no time (doing this all as an unpaid hobby now).
