hi im trying to make a zz4lep background with this model http://insti.physics.sunysb.edu/~curtin/hahm_mg.html

>import model HAHM
>generate p p > l+ l- l+ l- /h
>output background_zz4l500k
>launch
>detector=Delphes
>set mmll 4.0
>set nevents 500000

 but im failing with

Hi,

Your cut is not compatible with the level of optimization that we use for this process.
you have to reduce the level of optimization by either
1) change the model to have massive muon
2) run like this

set group_subprocesses False

Cheers,
