Phythia Takes no Events from MadGraphz

Asked by Nicholas Hurley

At high energies, my process (which contains decays) is able to output Delphes root files. However, when I lower the energies, I get the following error in my pythia log-file.

166 Abort from Pythia::next: processLevel failed; giving up |
 | 1 Abort from Pythia::next: reached end of Les Houches Events File |
 | 834 Error in ProcessContainer::constructProcess: setting mass failed |
 | 2 Info from SLHAinterface::initSLHA: No MODSEL found, keeping internal SUSY switched off |
 | 2 Info from SLHAinterface::initSLHA: importing MASS entries |
 | 2 Warning in SLHAinterface::initSLHA: ignoring DECAY tables |
 | 2 Warning in SLHAinterface::initSLHA: ignoring MASS entries |
 | 7 Warning in SLHAinterface::initSLHA: ignoring QNUMBERS |
 | 2 Warning in SLHAinterface::initSLHA: ignoring empty DECAY tables

What could be the cause of this? I've tried messing around with the xqcut parameter. Am I going in the right direction?

You should contact pythia author first, I do not know what such error means.
If they indicate that the error is on our side don't hesistate to came back to us with their findings.
