Import multiple models in the MG proc card

Asked by Ankita Mehta on 2020-06-16

Hi,

I am trying to simulate dimension 8 eft sample for the VBS with opposite-sign WW (fully-leptonic) events. I'd like to use the 5f scheme and a UFO model for aQGC. Since using the 5f scheme requires a model to be imported, I'm doing it like this in the proc card:

import model SM_Ltotal_Ind5v2020v2_UFO
import model sm-ckm_no_b_mass

could you please suggest if this is correct ?

many thanks,
ankita

Hi,

Importing a model, overwritte the previous one.
you have the command "add model" which is designed to merge two model in a single one but I would not recommend it in this case.
Please use the trick indicated in this FAQ to tune your model (in this case to remove the b-mass)

Cheers,

Olivier

Dear Olivier,

thanks a lot. Indeed, removing the no b-mass model resolves the issue.
