Reweighting aQGC in MG2.6

Hi,

Yes, it should be fine in 99% of the case. This is a line that check that everything is fine (i.e. it should always be True).
The problem is that we have two format for the model internally and looks like you have found a case where the type of model which does not have the function
to evaluate the mass is used.

Thanks I will secure this problem in next version of the code.

Cheers,

Olivier

Thanks Olivier Mattelaer, that solved my question.

Hi,

For reference, I have tested again using the current newest release, 2.6.2, and this problem still exist

-Robert

Hi Robert,

Then I would need that you provide to me the exact list of command that you use, since everything is working fine for me with that model (but I'm not even sure that I use the same model as you).

Cheers,

Olivier

This question was expired because it remained in the 'Needs information' state without activity for the last 15 days.

Hi Olivier,

Sorry for the delay on my end. I use the following card to generate the process:

import model sm-no_b_mass
import model SM_LS012
define p = g u c d s b u~ c~ d~ s~ b~
define j = g u c d s b u~ c~ d~ s~ b~
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
define w = w+ w-
generate p p > j j z z QCD=0 QED=4 NP=1
output aQGC_LS012_nodecay_reweight
launch
#### Set paramters
set FS0 1.0e-12
set FS1 0.0e-12
set FS2 0.0e-12
set FM0 0.0e-12
set FM1 0.0e-12
set FM2 0.0e-12
set FM3 0.0e-12
set FM4 0.0e-12
set FM5 0.0e-12
set FM6 0.0e-12
set FM7 0.0e-12
set FT0 0.0e-12
set FT1 0.0e-12
set FT2 0.0e-12
set FT3 0.0e-12

set FT5 0.0e-12
set FT6 0.0e-12
set FT7 0.0e-12
set FT8 0.0e-12
set FT9 0.0e-12

Then I add the following reweight_card.dat and run generate_events:

change mode LO
change model SM_LS012
launch --rwgt_name=FS0_10_test
  set FS0 10.0e-12
  set FS1 0.0e-12

  set FT6 0.0e-12
  set FT7 0.0e-12
  set FT8 0.0e-12

Which leads to this snippet from the output:

Hi,

When i do

it returns:

Which means that you model is NOT on the feynrules database (otherwise it should have been downloaded automatically.). So I change the model by LS012 which does exists in the FR website. If this is not the correct model, please tell me.

So i have written the following script to test your setup:

and indeed face a crash which sounds similar to yours.
I have applied the following modification to the code:

and the it was working.

Thanks for your help,
