effective hgg vertex get zero cross section
Dear Calchep experts
I implemented a new model with three Higgs doublets (two of them get vev, the other one is inert) in feynrules. Following closely the formulas for the effective hgg coupling that comes within the IDM of micromegas I wrote down the interaction as
g |g |h | |-4*Lggh*Rqcd_h |p1.p2*
in the lagrangian file where
LggH |-cabs(hGGeven(MH, aQCD_H, 3, 1, 3, MB, x212x0/MB, 1, 3, MC, x217x0/MC, 1, 3, MT, x218x0/MT))
Rqcd_h |sqrt(1+
The x212x0 functions are coupling hff with f the corresponding fermion.
when I calculate the cross section g,g->h using monte carlo integration in GUI session I obtain zero cross section.
Can someone please point out to me what am I doing wrong?
