Problem in generating WZ+jets and ttW+jets events

Asked by KP.Xie

Hi,

I met problems when generating events for WZ+jets and ttW+jets processes in the default SM model.

For the WZ+jets process:

generate p p > w+ z j j @1, w+ > l+ vl, z > j j
add process p p > w+ z j j j @2, w+ > l+ vl, z > j j
add process p p > w- z j j @3, w- > l- vl~, z > j j
add process p p > w- z j j j @4, w- > l- vl~, z > j j
output WZ+jets

and I set ptj=10, ptb=10, etaj=5, etab=5, cut_decay=True, and xptj=150. And it yielded:

Error when reading /home/kpxie/MG5_aMC_v2_6_3_2/Composite_resonance/WZ+jets/SubProcesses/P2_gq_wpzqqq_wp_lvl_z_qq/G5/results.dat

For the ttW+jets process:

generate p p > t t~ w+ j, t > b j j, t~ > b~ j j, w+ > l+ vl @1
add process p p > t t~ w+ j j, t > b j j, t~ > b~ j j, w+ > l+ vl @2
add process p p > t t~ w- j, t > b j j, t~ > b~ j j, w- > l- vl~ @3
add process p p > t t~ w- j j, t > b j j, t~ > b~ j j, w- > l- vl~ @4
output ttxW+jets

and the same run_card.dat with the WZ+jets process. It yielded a very similar error:

Could you try with the latest version?
It is possible that this is already fixed (I would say 50% chance that it is).

If not this is the kind of issue that takes couple of weeks to fix (at least).

Cheers,

Olivier
