Hi,

thanks a lot for having patched FeynArts 3.7 with FeynCalc 8.

However, I experience a trouble when I use the InsertionField[] functions with common SM topologies like simple boxes. This does not happen when I use the FeynArts 3.4
patched version.

The error message reads :

TagSetDelayed::tagnf: \\\“Tag FourVector not found in -mom_^mu___.\\\”

Thank you for any answer.

Sincerly,

Philippe Mertens
