In the complex 2-Higgs-Doublet Model (C2HDM), the mass m3 of the heaviest neutral scalar h3 is usually chosen as a derived parameter. We investigate one-loop corrections to m3 and their impact on decays of h3. Very fine-tuned regions of the parameter space can be found where such corrections are large, not due to subtraction schemes, but rather due to the particular dependence of m3 on the independent parameters. We show that even moderate corrections can have a significant impact on decays of h3, as they may be several times enhanced by leading-order factors.
