Description
Dear Experts,
I'm trying to do studies on the kinematics of the model https://feynrules.irmp.ucl.ac.be/wiki/LeptoQuark
and I have found a particularity in the channel
p p > j lq ta $ lq QCD=0, (lq > qb ta )
(you should see the attachments)
If I read the output *.lhe of madgraph, the leading jets (and that are not bjets) show a forward distribution in eta:

But if I read the output *.root of delphes, the leading jets have a central distribution.

I have observed this particularity for myself in madanalysis5 at the partonic level, and with pyroot at the hadronic level. I have also observed this particularity with the automatic analyses that are executed when we ran madgraph. We think that while it is common for the distribution to change at different levels, it is abnormal for it to occur so drastically, and we think it may be a bug.
Thanks & Regards,
Cristian R.
