Hello,I have written a FeynRules model and used FeynArts to create diagrams and finally FeynCalc to regularize the amplitude but the are strange gauge parameters “Subscript[\[Xi], S(Gen3)]”,…. appearing in the amplitude.I have just one massless vector V[1] and setting GaugeXi to 1 does not help getting rid of these.Please help me with this.
