Abstract
This report reviews the properties of Higgs bosons in the Standard Model (SM)and its various extensions. We give an extensive overview about the potentialof the ILC operated at centre-of-mass energies up to 1 TeV (including the gammagamma option) for the determination of the Higgs boson properties. Thiscomprises the measurement of the Higgs boson mass, its couplings to SM fermionsand gauge bosons, and the determination of the spin and the CP quantum numbersof the Higgs. The extensions of the SM that are analyzed in more detail areheavy SM-like Higgs bosons, heavy Higgs bosons in the framework ofSupersymmetry (SUSY) and further exotic scenarios. We review recent theoreticaldevelopments in the field of Higgs boson physics. The important question whatthe ILC can contribute to Higgs boson physics after the LHC, the LHC/ILCinterplay and synergy is discussed. The impact of Higgs boson physics oncosmology in several SUSY frameworks is analyzed. The impact of the acceleratorand dector performance on the precision of measurements are discussed indetail. We propose a strategy to optimize future analyses. Open questionsarising for the various topics are listed, further topics of study andcorresponding roadmaps are suggested.
