merging models
Hi,
I have two questions.
1. I have generated a UFO file with feynrules, consisting of higher dimensional operators of Standard Model particles. As I am importing this file in MG5_aMC_v2_6_6, I get the following warning:
MG5_aMC>import model higgs_dim6
INFO: failed to load model from pickle file. Try importing UFO from File
INFO: load particles
INFO: load vertices
CRITICAL: Model with non QCD emission of gluon (found 36 of those).
This type of model is not fully supported within MG5aMC.
Restriction on LO dynamical scale and MLM matching/merging can occur for some processes.
Use such features with care.
INFO: Change particles name to pass to MG5 convention
Kept definitions of multiparticles l- / j / vl / l+ / p / vl~ unchanged
Defined multiparticle all = g a ve vm vt ve~ vm~ vt~ u c t d s b u~ c~ t~ d~ s~ b~ z w+ h w- e- mu- ta- e+ mu+ ta+
MG5_aMC>
Such a warning does not appear in previous versions of MG5_aMC. Could you explain why it appears and what it means? Is it fine to work with this ufo or do I need to look to rectify it?
2. I am trying to generate process g g > h z with my ufo file 'higgs_dim6' and also study its interference with sm at tree and one-loop level. So, for sm part I can get this process with loop_qcd_qed_sm:
>import model loop_qcd_qed_sm
>generate g g > h z [noborn=QED]
The above process occurs at tree and one-loop level. I wish to study it with my model. So, as I am adding model with 'add model ' command I get the following error:
MG5_aMC>import model loop_qcd_qed_sm
Switching to Feynman gauge because it is the only one supported by the model loop_qcd_qed_sm.
INFO: Restrict model loop_qcd_qed_sm with file models/
INFO: Run "set stdout_level DEBUG" before import for more information.
INFO: Change particles name to pass to MG5 convention
Pass the definition of 'j' and 'p' to 5 flavour scheme.
Kept definitions of multiparticles l- / vl / l+ / vl~ unchanged

MG5_aMC>add model higgs_dim6_plugin
Command "add model higgs_dim6_plugin" interrupted with error:
USRMODERROR : Base Model doesn't follows UFO convention
Please report this bug on https:/
More information is found in 'MG5_debug'.
Please attach this file to your report.
Is it not possible to merge loop model with any other ufo model. Could you please suggest any solution?
