Abstract
The precision measurements of Higgs boson observables will be critical in the interpretation of the dynamics responsible for electroweak symmetry breaking. The capabilities of the ILC and CLIC for precision Higgs studies are well documented. In this talk, a theoretical framework is presented for interpreting phenomena that can arise in the two-Higgs-doublet model (2HDM). By imposing no constraints on the most general set of 2HDM parameters, the resulting formalism correctly identifies the physical 2HDM observables, which can be determined by model-independent experimental analyses.
