Related to warning in CheckMassSpectrum[LTot] command

Asked by SUBHASISH BEHERA

Dear MG5 team,
      I encounter an error while I tried to generate an UFO model file of my own. The following are the details :

CheckMassSpectrum[LTot]
Neglecting all terms with more than 2 particles.
All mass terms are diagonal.
Warning: mass term for {D0, D0}seems not to have the correct sign.
Warning: mass term for {Dch, Dchbar}seems not to have the correct sign.
Warning: mass term for {ghZ, ghZbar}seems not to have the correct sign.

So my question is :
 Why this is coming here and how this will effect my processes ?

Thanks,

Subhasish

Dear Subhasish,

I guess that you are confusing MG5aMC with FeynRules. Such command/warning are clearly not generated by our code.
This looks like that your are using FeynRules (is it?) If so I would suggest that you contact the FeynRules author.

Cheers,

Olivier
