Default parameter card produces an error (in loop_sm-no_b_mass)

Asked by Marc de Beurs

Dear experts.

Recently I have updated my MG to the latest version 2.5.4. However now I get an error when running the loop_sm-no_b_mass model, with the default cards.

It claims that it requires the yukawa block in the parameter card. However, adding this manually to the parameter card, the error remains...

Afterwards I tried to reinstall madgraph from scratch, downloading the latest version from the home page. And still this error is present.

This is the exact process that I am trying to run:

import model loop_sm-no_b_mass
set complex_mass_scheme True
generate p p > p w+ b $$ w+ w- z a QED=3 [QCD]

And the error that I get is:

Command "launch auto " interrupted with error:
MadGraph5Error : Invalid restriction card (not same block)
     set(['sminputs', 'mass', 'loop', 'decay']) != set(['yukawa', 'sminputs', 'mass', 'loop', 'decay']).
     Missing block: yukawa
     Unknown block :
Please report this bug on https://bugs.launchpad.net/mg5amcnlo
More information is found in 'ME5_debug'.
Please attach this file to your report.

Running this process at LO (generate p p > p w+ b $$ w+ w- z a QED=3 QCD=0)
The same error occurs, but only when I want to decay the obtained events using MadSpin.
The generation step in MG then works fine

Cheers Marc

Hi,

I do not reproduce such problem (neither the MadSpin problem nor the NLO one).
Can you create a bug report and attach the debug file for each case?

Cheers,

Olivier

Hi Olivier,

Setting "complex_mass_scheme = True" in the proc_characteristics file inside the SubProcesses folder, solved my problem.

Thanks for your help.
Cheers Marc

Ok then I guess that I know what your problem was, and I think that this should be fixed in the next version.
If you want to be sure. Please attach your debug file, such that I can indeed reproduce your problem

Cheers,

Olivier
