Hello,

here is my summary:

      Process p p > l+ vl [QCD] @0 ; p p > l- vl~ [QCD] @1 ; p p > l+ vl j [QCD] @2 ; p p > l- vl~ j [QCD] @3
      Run at p-p collider (50000.0 + 50000.0 GeV)
      Number of events generated: 50
      Total cross section: 1.570e+05 +- 2.9e+03 pb

What do you think?
is that problem about pythia8 & main82.cc sample or it is about MG?

Thank you.

Hi,

Which version of MG5aMC are you using?
Which version of PYTHiA8 are you using?
What is the content of the associate debug file: /Users/test/nlo2/MCatNLO/RUN_PYTHIA8_2/mcatnlo_run.log
What is the content of the standard MG5aMC debug file: /Users/test/nlo2/run_02_tag_1_debug.log

A priori this sounds a pure PY8 error. But I do not have enough information to be sure. (and it is not allowed to attach file for question -- it is for bug report so if you want to attach such files, please convert this thread to a bug report(

Cheers,

Olivier
