 Finally in this case we have considered the possibility of having a heavy scalar H (called hh in the MG files) as an intermediate state (so that we have the additional process p p > hh > h h that is taken into account). For this model in the paramcard you have the freedom of modifying a wide range of parameters :
 * the top yukawa coupling (via the parameter cy)

 * the H coupling to the top (cyH)
 * the H coupling to 2 SM-Higgs (ctrH)
-The parameters cy and ctr are just factors that multiply the SM couplings. The parameters cyH and ctrH are similarly used but for the new heavy Higgs. Finally you can also modify :
+The parameters cy and ctr are just factors that multiply the SM couplings. The couplings for the heavy scalar are obtained similarly by multiplying the corresponding SM couplings with the parameters cyH and ctrH. By default they are all fixed to 1.
