FeynArts not working properly
I've just uploaded a new version which again should support loading FeynArts, so that FeynCalc and FeynArts can be used from the same session - which I personally find very convenient.
See
http://www.feyncalc.org/download/
and
http://www.feyncalc.org/cgi-bin/diary.pl
FeynArts-3.7 is bundled with the release, so you can simply load FeynCalc with
$LoadPhi = True;
$LoadFeynArts = True;
<< HighEnergyPhysics`FeynCalc`;
The first time you do this, FeynArts will be patched to avoid name clashes etc. After that you can in principle load FeynCalc+FeynArts without loading PHI, but then you should manually do
SetOptions[FourVector, FeynCalcInternal -> False];
before
InitializeModel[SM]
Otherwise FeynArts will complain and not load correctly
because of
FourVector /: -FourVector[mom_, mu___] := FourVector[Expand[-mom], mu]
in "Lorentz.gen".
