     43We calculated the H bosons pair production through gluon fusion at LO in the Two Higgs Doublet Model, allowing the following 7 final states: hh,hH,HH,hA,HA,AA,H+H- where h (H) stands for the light (heavy) scalar boson and A is the pseudoscalar neutral boson. This model contains the exact form factors at LO for the triangle loop and the box as given in [http://arxiv.org/abs/hep-ph/9603205 arxiv:9603205] [hep-ph] and [http://arxiv.org/abs/hep-ph/9707430 arxiv:9707430] [hep-ph] and includes both contribution of top quark and bottom quark in the loop.

     45It is important to note that in this model we didn't restrict ourselves to the more constrained MSSM, which means for example that the masses of the 5 new bosons are left as free parameters, as well as all their extended Yukawa coupling to top and bottom quarks (expressed as rescaling factor with respect to their SM value) so that they can be changed at will in the parameter card for any phenomonological study.
