madspin two decay paths
Dear experts,
I have the following process within madgraph:
generate p p > t t~, (t > w+ b, w+ > l+ vl), (t~ > w- b~, w- > j j)
add process p p > t t~, (t > w+ b, w+ > j j), (t~ > w- b~, w- > l- vl~)
Now for several reasons I have to apply the same decay but then with madspin. Is this possible and if so, what is the madspin lines for this? I tried the following but it didn't give the same results as the above:
process_card:
generate p p > t t~
madspin_card:
decay t > w+ b, w+ > j j, t~ > w- b~, w- > l- vl~
decay t > w+ b, w+ > l+ vl, t~ > w- b~, w- > j j
Thanks in advance.
Kind regards,
Pim

Hi,
No this is not possible with madspin without having two separate generation.
Cheers,
Olivier
