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
