     21We calculated the gluon-gluon fusion contribution to Zh_i production (where h_i stand for (h,H,A) with the usual notation: h for the light scalar neutral boson, H for the heavy one and A for the pseudoscalar boson). Like in the SM this is part of the NNLO QCD corrections to ZH production in proton-proton collisions. We also used exactly the same technique as before (reweighting of the EFT).

     27In the 2HDM there is one additionnal diagram contributing to Zh production with respect to the SM above: the s-channel A contribution.
