Description
Precision measurements of Higgs interactions provide one of the most powerful avenues to probe physics beyond the Standard Model (SM). In this talk, I will present automated one-loop calculations of the Higgs trilinear self-coupling and the $hZZ$ coupling within the Two Higgs Doublet Model (THDM) framework. This analysis is particularly relevant in view of future experimental facilities, where percent-level precision will make loop effects indispensable. It clarifies the interplay between different Higgs observables and identifies which measurements offer the strongest sensitivity to new physics effects.
