Problem with NLO event production

Asked by Andreas Kirchhoff on 2017-11-08

Dear MadGraph Team,

just for test purposes I tried to generate the following process:
generate u d~ > e+ ve [virt=QCD]
Everything went fine until I wanted to generate the events by the launch command. I work on the lxplus-system of the ATLAS collaboration.
Here is the complete dialog:

Hi,

First note that you can not generate any events for the following syntax:
> generate u d~ > e+ ve [virt=QCD]
For that process definition (loop only), you can only compute the value of the loop (the finite, then single and double pole) for a given phase-space point.

Your problem seems related to collier. Are you sure that this program is correctly installed in the path that you configure for it?
> /afs/cern.ch/work/a/ankirchh/private/MadGraph/MG5_aMC_v2_6_0/HEPTools/collier

Did you retry to install it?

Cheers,

Olivier

Hi Olivier,

I tried to reinstall collier (see line 17 in the document in the appendix). Afterwards I followed the instructions given on this webpage: https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/MadLoopStandaloneLibrary
But I just generated the first process. The output command works normal as before but the launch command (see line 130) gives the same error. I put the whole output from the console into the appendix.

Betreff: Re: [Question #660471]: Problem with NLO event production

Your question #660471 on MadGraph5_aMC@NLO changed:
https://answers.launchpad.net/mg5amcnlo/+question/660471

    Status: Open => Answered

Olivier Mattelaer proposed the following answer:
Hi,

First note that you can not generate any events for the following syntax:
> generate u d~ > e+ ve [virt=QCD]
For that process definition (loop only), you can only compute the value of the loop (the finite, then single and double pole) for a given phase-space point.

Your problem seems related to collier. Are you sure that this program is correctly installed in the path that you configure for it?
> /afs/cern.ch/work/a/ankirchh/private/MadGraph/MG5_aMC_v2_6_0/HEPTools/collier

Did you retry to install it?

Cheers,

Olivier
