Very different cross sections for g g > w+ w- s s~ and g g > w+ w- b b~ with 5FS
Asked by

Dear MG5 Team,
I'm generating the following processes, and I'm getting very different cross-sections:
g g > w+ w- s s~
xsec: 0.185 pb
g g > w+ w- b b~
xsec: 405.9 pb
I'm using MG 2.7.2, and in both cases I'm setting:
set maxjetflavor 5
set param_card mb 0
set param_card ymb 0
set cut_decays True
I'm wondering why such a big difference.
Thanks very much!
Nick
