Bug Description
I'm trying to run a process in the frame of e+ e- collider specifically for CLIC experiment. I did some runs of my model in the stage 1 and 2 of CLIC, it is 0.380TeV and 1.5TeV for the center of mass energy, and everything was working more than right. However when I try to run the stage 3 for 3TeV for the center of mass energy, I get much less events than asked, from 10000 I get between 20-100 events. Something that puzzles me is that whenever I ask for 100 events or less everything works out. I really do not have any clue of what is happening, do you have any limit for the center of mass energy? Any clue will be really very welcome.
PS. I do not receive any error message at all.
Thanks a lot for your help,
Karla

To post a comment you must log in.
You seem do not have any cut on the lepton. (or do I miss some)
and your chi is quite soft compare to your center of mass.
So you might have some extremely forward lepton which are likely to be undetected experimentally and which might lead to code unefficiency (or maybe numerical divergence).
So I would suggest to add a pt cut to see if this improves the situation.
Cheers,
Olivier
