Crashing while produce ttH (H to tt) process
Dear MG5 Team,
I am trying to generate event for ttH off shell to tt process, I am running with MG5_aMC_v2_7_2 and using sm model.
Here is lines how I generate this process:
generate p p > h > t t~ t t~
I also set the bwcut to be 300 GeV in both madspin and run parameter card
When decaying the events:
And I get the following error message:
ERROR: Found a weight MUCH larger than the computed max_weight (ratio: 1659.96832792).
This usually means that the Narrow width approximation reaches it's limit on part of the Phase-Space.
Do not trust too much the tale of the distribution and/or relaunch the code with smaller BW_cut.
This is for channel ('t_wpb_wp_csx', 'tx_bxwm_wm_scx', 't_wpb_wp_csx', 'tx_bxwm_wm_scx') with current BW_value at : 297.901'
Command "generate_events run_02" interrupted with error:
IndexError : list index out of range

I am just wonder how I can fix such a problem here.
Thanks in advance!
