On two-loop corrections to the Higgs trilinear coupling in models with extended scalar sectors
We investigate the possible size of two-loop radiative corrections to the Higgs trilinear coupling λhhh in two types of models with extended Higgs sectors, namely in a Two-Higgs-Doublet Model (2HDM) and in the Inert Doublet Model (IDM). We calculate the leading contributions at two loops arising fro...
