MadGraph5_aMC@NLO

particle pdg error code

Asked by Disha Bhatia on 2018-04-05

Hi,

I am implementing a model which is somewhat like 2HDM+ a complex scalar in Madgraph using Feynrules.
I have three CP even scalars which I named h1, h2, h3 and assigned pdg codes 25,35,45 as per nmssm convention.
and two CP odd scalars A1, A2 which I assigned ppdg codes 36, 46.

The error which I am getting while importing the UFO file is:
h3 particles with pdg code 45 is in conflict with MG convention name for particle 36.
In usual 2HDM madgraph convention h3 is actually my A1 particle.

I also tried assigning names like ha, hb, hc - but madgraph is by default changing names to pass its conventions.

The suggestion which was shown was Use -modelname in order to use the particles name defined in the model and not the MadGraph5_aMC@NLO convention

But I didn't understand where to use -modelname?

Can you please help me with this problem?

Thanks,
Disha
