VBF_NLO process failing due to poles not cancelling

Asked by Dhruvanshu Parmar

I am trying to generate VBF process at NLO level:
```
MG5_aMC>generate p p > h j j $$ w+ w- z [QCD]
Setting the born squared orders automatically in the process definition to QED^2<=6 QCD=0.
If this is not what you need, please regenerate with the correct orders.
WARNING: Use of multiparticles is non-trivial for NLO process generation and depends on the orders included, the process considered, as well as the PDF set chosen. See appendix D of arXiv:1804.10017 [hep-ph] for some guidance.

```

If I am interpreting the error correctly, there are some instances where there is division by zero which is making that computation fail. Could there be some diagrams responsible for this??

Thanks,

Hi,
I would suggest you to do the following:
re-generate the process with
set nlo_mixed_expansion F
before the generate/output command

This will include only loops with QCD particles, and not the pentagons, which are anyway either zero or suppressed

Then, your generation will be identical to what was done with MG5_aMC v2.x, and you can find more informations about VBF/VBS type processes here
https://arxiv.org/pdf/1803.07943.pdf
and https://arxiv.org/pdf/2003.12435.pdf

Let me know if you need more.

Best,

marco

Hi Marco,

I did what you suggested, i.e. :
```
set nlo_mixed_expansion F
generate p p > h j j $$ w+ w- z [QCD]
output
launch
```

It removed a lot of diagrams, as many of them werent pure QCD loops. But the problem of poles still remains:

Hi,
the fact that poles do not cancel is normal for this process.
You can disable the pole check by setting the value of the
IRPoleCheckThreshold and PrecisionVirtualAtRunTime parameters in the
Cards/FKS_params.dat file to -1. (see also the paragraph about MG5_aMC in
sect 3.2 here https://arxiv.org/pdf/1803.07943.pdf)

Cheers,

Marco Zaro

Hi Marco,

I saw the section relevant and made the following changes in the FKS_param.dat card. I probably didnt do it the right way, because now the process is terminating due to a Fortran error.
1) Modified FKS_param.dat:
```
! ==========================================================================
! This file sets the different technical parameters intrinsic to the
! FKS program and which controls the behaviour of the code at run
! time. The common user should not edit this file and only experts
! should venture editing these parameters.
! ==========================================================================
!
! ==========================================================================
! Parameters controlling the tests based on the IR poles comparison
! ==========================================================================
!
! This threshold sets the limiting value for the comparison of the
! relative difference of the IR pole from the OLP and the one computed
! internaly by MadFKS. The value below is used for the first PS
! points to assess the sanity of the computation. A value ten times

Hi Marco,

My bad, I thought the commented line wont be read by the code.

Thanks for all your help. That indeed solved my problem. Now the process is executing fine without any interruption or error.

Thanks,
