Fixing coupling parameters to the same values
I am trying to compare the results of MadDM with the paper https:/
In particular I am focusing on the model DMsimp_s_spin0. That paper is the reference for that model.
I would like to make the plot in figure 5 top left with the g^S_DM as a function of g^S_SM and the curve related to omega_DMh^2<0.11. I am trying to calculate the relic density by varying g^S_DM and g^S_SM with a scan.
I have seen that the parameter g^S_DM is gsxd (for xd dark matter particle). Instead the parameter g^S_SM is actually divided in several parameters in the model because the mediator Y0 interacts with the quarks, gauge bosons and Higgs. So there is one parameter for each of this couplings. I know that for the relic density calculation what matters is the coupling with the Gauge boson, Higgs and top quark (gsb, gsh1, gsu33). Is there a way to make the three parameters to be the same in the scan of g^S_SM?
In this way I can make a scan of g^S_DM and g^S_SM.
Thanks for the consideration!
