Hello. I recently started using feyncalc for training purposes. My naive
problem is that when I use the function, the Contract convolves the
four-vector index and Levi-Civita, although I changed it as follows
SetOptions [Contract, EpsContract -> False]
and when I enter Options [Contract], EpsContract -> False is
displayed. Even if I explicitly write out
Contract[LC[\[Alpha], \[Beta], \[Mu],
\[Nu]]*FV[p, \[Nu]],
EpsContract -> False]
it turns out
\[Epsilon]^(\[Alpha]\[Beta]\[Mu]Overscript[p,
_]).
How to make the indexes do not fold with Levi-Civita? Thank you very
much
