LCD

Description

LCD[m,n,r,s] evaluates to D-dimensional LeviCivita[m,n,r,s] by virtue of FeynCalcInternal. LCD[m,...][p, ...] evaluates to D-dimensional LeviCivita[m,...][p,...] applying FeynCalcInternal.

You need to do SetOptions[Eps, Dimension->D] before LCD can be used as D-dimensional Levi-Civita input function.
