Showering with Pythia in NLO

Asked by Can Süslü

Hi,

I would like to produce NLO events. I have questions regarding them:

1-) When choose Herwig as the parton shower, I only get an .hep file. I want to analyze the data in Rivet, so I would like to get an .hepmc file? How can I do this?

2-) When I choose Pythia as the parton shower, I get an error while the program goes to the showering step. Here is the log file that I get:

I do not know that answer, converter should exists between those two formats.

2-) When I choose Pythia as the parton shower, I get an error while the program goes to the showering step. Here is the log file that I get:

What is the content of /home/suslu/CAN_MC_Programs/MG5_aMC_v3_3_2/amcatnlo_run.log
It should contain the real problem.

Cheers,

Olivier

Dear Olivier,

In /home/suslu/CAN_MC_Programs/MG5_aMC_v3_3_2. path, there is only a ME5_debug file. Debug file contains what I have first post in here.

In the path of the corresponding run, (/home/suslu/CAN_MC_Programs/MG5_aMC_v3_3_2/znlo) there is a mcatnlo.log file. It contains:

Dear Olivier,

I would like to report one more thing about the problem. Although I am able to generate .hep files showered with Herwig at NLO, after I switch to Pythia8 and having obtained an error, the Herwig also does not work properly for that process. I would like attach that .log file, after I try to use Herwig for the second time :

Did you update the compiler?

herwig6 is a pretty old/unsupported code. So the code for herwig6 is fully frozen by now to outdated coding practise.
Some of them have been now fully forbidden by some recent compiler...
And the error that you report for herwig6 is one of those.

For pythia8, I do not see any information in the log. So I'm quite blind. Due to your next post, I guess that it might related to some of the dynamical library of pythia8 compiled with another version of the compiler (or for another architecture in the case if you are using one of those recent mac)

Dear Olivier,

I get this error from Herwig only when I first try to compile the process using Pythia. When I first use Herwig, it just works fine. Maybe pythia just disrupts the compiler, and I get this error. I will try to link an external Pythia path instead of using the pythia installed from the mg5 interface.

Regarding the version of herwig, I actually would like to use Herwig7 or Herwig++ since they output hepmc format instead of stdhep. Can I install those versions in the Mg5 interface using install command? Or do I have to link them externally?

Thanks a lot,
Can Suslu

You are right, those seems to still be warning and not crash with your compiler. Sorry.

AhI see, I guess that setting pythia, trigger automatically some flag to be added in the shower_card.dat (because we know that we need those for pythia8) and then when you switch back to herwig those flag are not remove and lead to the compilation crash for herwig...

We do not have an "install herwig7" so you will need to update the file input/mg5_configuration.txt to specify the path of the PEG and of the herwig code. I have never done that myself, but if you have issue, i will assign this to our HW7 expert.

Dear Olivier,

It would be good indeed, because I get some errors regarding the installation of ThePEG and Herwig, and the reason seems like a problem occurs while installing LHAPDF6. Here is the error below:

Since there is an error in LHAPDF, I can't compile the PEG, are there any solution of this?

Also, I have tried linking an external pythia8, however I get the same errors in NLO production which I have posted here. Also, I get a warning saying that:

WARNING: Trying to shower events using the same PDF in the shower as used in the generation of the events using LHAPDF. However, no valid LHAPDF installation found with the needed PDF set. Will use default internal PDF for the shower instead. To use the same set as was used in the event generation install LHAPDF and set the path using "set /path_to_lhapdf/bin/lhapdf-config" from the MadGraph5_aMC@NLO python shell

Could the problem I get in Pythia also be related to LHPDF?

Thanks a lot,
Can Suslu

This means that you need to install python-dev package (from yum/apt-get)

For the issue with pythia8, if you do not have lhapdf then yes it is problematic, but you technically do not need python integration for lhapdf to be working for pythia8 (as long as I know). This is an optional feature of lhapdf.

Cheers,

Olivier
