Merging two models

Asked by Umut C Oktem on 2018-07-18

Hi,

I am trying to run an event where the standard model like higgs in the MSSM decays into two photons. For this, I am using the alpha code written here https://code.launchpad.net/~maddevelopers/mg5amcnlo/plugin_model to merge the heft model with the mssm model. But when I run the code and enter the command "add model heft --output=new_model" after importing mssm, it gives me the following error:

"INFO: The two model defines the parameter 'MH'
      the original model for MASS :[37]
      the plugin for MASS :[25]
      We will rename the one from the plugin to MH__1
INFO: The two model defines the block 'MASS' with id '[25]' with different parameter name 'MH__1', 'MH01'
     We will merge those two parameters in a single one

Is there a way to fix this issue without resorting to merging the two models by hand in Feynrules? Thanks.

Hi,

Why are you using?
https://code.launchpad.net/~maddevelopers/mg5amcnlo/plugin_model
This was merged within the official version of MG5aMC in 2014 and any update related to such functionality occurs directly in MG5aMC.

So can you try to do the same within the latest version of MG5aMC?

Actually to minimise conflict when you add model, you should rather do
add model hgg_plugin

Cheers,

Olivier

Thanks Olivier Mattelaer, that solved my question.
