  The ILC Higgs White Paper is a review of Higgs Boson theory and experiment at
the International Linear Collider (ILC). Theory topics include the Standard
Model Higgs, the two-Higgs doublet model, alternative approaches to electroweak
symmetry breaking, and precision goals for Higgs boson experiments.
Experimental topics include the measurement of the Higgs cross section times
branching ratio for various Higgs decay modes at ILC center of mass energies of
250, 500, and 1000 GeV, and the extraction of Higgs couplings and the total
Higgs width from these measurements. Luminosity scenarios based on the ILC TDR
machine design are used throughout. The gamma-gamma collider option at the ILC
is also discussed.
