DiracSlash[p]
is the contraction (FV[p, mu] GA[mu]
).
Products of those can be entered in the form GS[p1, p2, …].
The shortcut DiracSlash is deprecated, please use GS instead!
This is -slash, i.e.,
[q] DiracSlash
[p] . DiracSlash[q] DiracSlash
[p, q] DiracSlash
DiracSlash is scheduled for removal in the future versions of FeynCalc. The safe alternative is to use GS.
[p] GS
[p] GSD
[GS[p]] === DiracSlash[p] FCI
[GSD[p]] === DiracSlash[p, Dimension -> D] FCI
