Hi,
Thanks for all the help!
So my real problem is how to modify the code which I posted in my
first message to prevent all these trivial contractions of LeviCivita
tensors from appearing. Since for the process which I want to evaluate,
9 terms would come out. I just don’t want to replace the trivial
LeviCivita tensors one by one.
Furthermore, after checking FeynCalc manual, I think the function
EpsEvaluate might help. But it doesn’t work correctly. For example,
“LC[][p1, p2, p3, p1 + p2] // EpsEvaluate”â€?
gives” -\[Epsilon]^(p1p2p1+p2p3) “ rather than”
-\[Epsilon]^(p1p2p1p3)+â€?-\[Epsilon]^(p1p2p2p3)”.â€?â€?
I am using FeynCalc 8.2.0 with Mathematica 9.0 on Win7(64bits).
Thanks for more help.
Best Regards!
Lingxiao
