error for delphes.lhco events file

Asked by vaborla

Hello,

         I produce the gamma+jet process using mg5 and phthia-delphes. I also matched the cross section setting xqcut=10,qcut=15. But there are some erros when I passed delphes.lhco file to MadAnalysis, like that

        ----------------------------------------------
               events information
 ----------------------------------------------

   Events in file : 49999
   Integrated weight (pb) : 0.14435000000000001
   Max wgt : 1.0000000000000000
   Average wgt : 1.0000000000000000

   Passing the cuts (plotted)
   --------------------------

   Events : 49999
   Integrated weight (pb) : 0.14435000000000001
   Max wgt : 1.0000000000000000
   Average wgt : 1.0000000000000000

Actually, the cross section after matching is 144350pb.

I refered to the problem https://answers.launchpad.net/madgraph5/+question/218692. Insteading of bin/generate_events, I use bin/madevent, but the mg5 shows "lauch in debug mode".

I have no ider what I should do.

Thanks
Violin

Hi,

I think that the problem is that the .lhco output file didn't contains any events.
Could you confirm that.
If this is indeed the case, the problem was reported to the Delphes team.

Cheers,

Olivier

Hi,

    I have seen the delphes.lhco file. I found that there are many non-empty events in the file.
