cross section much smaller than expected
I 'm working with MG5_aMCv2.7.3 to generate a process with 2HDMtII_NLO model .
With both ebeam =7000.0 ,I type generate p p > h+ h+ j j , ( h+ > w+ h1 , ( w+ > l+ vl ) , ( h1 > b b~ )), and set h+=205Gev ,h1=65Gev,the cross section is 1.237e-07fb which is two orders of magnitude less than I expected.
I'm trying to find the problem by working it step by step. Until I type generate p p > h+ h+ j j , ( h+ > w+ h1 , w+ > l+ vl ),the cross section is 2.768e-05fb,which is good enough for BR( h1 > b b~ ) is about 0.9 as I expected.
Next I calculate BR( h1 > b b~ ) by compare h1 > b b~ with h1 > all all using the same set. The width( h1 > b b~ )=0.06719Gev and width ( h1 > all all )=0.0705Gev so BR( h1 > b b~ )=0.953.
So I think the cross section of the process p p > h+ h+ j j , ( h+ > w+ h1 , ( w+ > l+ vl ) , ( h1 > b b~ )) should be
2.768e-
PS. the cut_decays in run_card is already set to True.
THANKS!!!!!

> PS. the cut_decays in run_card is already set to True.
It typically need to be set on False for such type of computation otherwise you do not have the same cuts between the various process. In particular what is your cuts on jet/bjets?
Cheers,

Sorry I was distracted . The correct "PS" which I want to express just now is: PS the cut_decays in run_card is already set to False. But I just tried to set it on True , the cross section doesn't changed so much.
The run_card.dat for process p p > h+ h+ j j , ( h+ > w+ h1 , w+ > l+ vl , h1 > b b~ ) with 2HDMtII_NLO model is (cross section is 1.19e-0.7).
