Madspin with spinmode=none does not properly load model restriction

[Josh Bendavid]

When running madspin with spinmode=none (in mg_aMC@NLO 2.3.2.2) it looks like the generated process for the decays are using the model default, rather than the appropriate model restriction.

(noticed this when trying to use "-lepton_masses" variations on some of the models to do higgs decays with massive leptons)

Proposed fix attached.

Hi Josh,

Thanks for the report/patch.
However I do not think that your patch is general enough.
the correct replacement should be “modelpath+restriction” instead of “name”.
The problem with “name" happens if someone use a model which is not in the models directory of madgraph.

Cheers,

Olivier
