By reconstructing WW and ZZ final states, not only the h to gamma-gamma partial width but also the phase of the scattering amplitude can be measured. This opens a new window onto the precise determination of the Higgs-boson couplings.Presented at the International Workshop on Linear Colliders LCWS(2002), Jeju, KoreaHigh Energy Physics - Phenomenologytext
