semileptonic top pair decay pro_card in MadGraph4

Asked by Juan Pablo Gomez

Dear all, I am trying to run the generator for the semileptonic top pair decay in MadGraph 4 but I haven't been able, I could do this in MadGraph 5 in the following way:
generate p p > t t~ QED=0, \
(t > W+ b, W+ > j j), \
(t~ > w- b~, W- > l- vl~)
output
But when I write in MadGraph 4 something like this:
pp>(w->l- vl~)(w+>jj)bb~
I get an error.
Could you please help me with this?
Thanks in advance,

JP

Hello Juan,

The corresponding process in MG4 is
pp>(t>(w->l- vl~)b)(t~>(w+>jj)b~)
Did you try this?

All the best,
Johan

Hi Johan, thank you very much. I put pp>(t~>(w->l- vl~)b-)(t>(w+>jj)b) and it worked perfectly.
Cheers,

JP
