Error finding propagator module after recent MG5 update

Hi,

I guess that the easiest way to fix this is to do
touch /home/mmanighalam/MadGraph5_v1_5_11/models/nmssm/propagators.py

Cheers,

Olivier

Hi,

I did what you said and ended up getting the following error:

Command "import /home/mmanighalam/MadGraph5_v1_5_11/Whiggs/Cards/proc_card_mg5.dat" interrupted in sub-command:
"import model nmssm -modelname" with error:
AttributeError : 'module' object has no attribute 'all_propagators'
Please report this bug on https://bugs.launchpad.net/madgraph5
More information is found in 'MG5_debug'.
Please attach this file to your report.

and the MG5_debug file says this:

.
.
.
File "/home/mmanighalam/MadGraph5_v1_5_11/models/import_ufo.py", line 167, in import_full_model
    ufo_model = ufomodels.load_model(model_path, decay)
  File "/home/mmanighalam/MadGraph5_v1_5_11/models/__init__.py", line 37, in load_model
    __import__(path_split[-1])
  File "/home/mmanighalam/MadGraph5_v1_5_11/models/nmssm/__init__.py", line 19, in <module>
    all_propagators = propagators.all_propagators
AttributeError: 'module' object has no attribute 'all_propagators'

                          ----------------
        complex_mass_scheme : False
               stdout_level : 20 (user set)
         group_subprocesses : Auto
.
.
.

I think the problem may just be that I don't have the propagators.py file that I need for this to work. Is there somewhere I could get this file? What do you think?

Thanks,
Michael

Here you are:

http://bazaar.launchpad.net/~madteam/mg5amcnlo/series2.0/download/head:/propagators.py-20131221104635-aw2d8nelbe7otbwz-1/propagators.py

So much trouble for a file which is not used....

Cheers,

Olivier

Hi,

Thanks Olivier, that solved the import and attribute errors that I was getting. I was wondering if you could help me with another problem as well? Now I am getting the following error:

Command "import /home/mmanighalam/MadGraph5_v1_5_11/Whiggs/Cards/proc_card_mg5.dat" interrupted in sub-command:
"generate g g > h01, h01 > a01 a01, (a01 > tau+ tau-)" with error:
InvalidCmd : No amplitudes generated from process Process: g g > h01 WEIGHTED=2
   Decay: h01 > a01 a01
   Decay: a01 > tau+ tau-. Please enter a valid process

I'm not sure, but does MadGraph include the gg > h01 coupling?

Cheers,
Michael

Hi Olivier,

Thanks for the information. Has the beta version implemented any higher order corrections?

Cheers,
Michael

Yes but we don’t have yet support for loop induce process, and we don’t even think about a double loop like yours.

Cheers,

Olivier

Hi Olivier,

I have downloaded the beta version that you linked. Could you please add the h a a vertex?

Thanks,
Michael

Dear Michael,

Sorry mis-configuration of my email send this email on my spam folder. So I only see it today.

So below you will find the patch that you can apply to have the haa in top of the hgg one.

Sorry for that,

Olivier
