Descripción
At center of mass energies of 500 GeV and above, e+e- collisions lead to processes in which the Higgs boson is radiated from top quarks and antiquarks and events in which two Higgs bosons are produced. The first of these processes leads to a precision measurement of the Higgs boson coupling to top quarks, the second to a measurement of the Higgs boson self-coupling. The rates of these processes are small, but linear colliders offer many tools to extract the signal processes from background, including highly efficient flavor tagging, the full reconstruction of top-antitop systems, precise control of (3-dimensional) missing energy, control of initial beam polarization, and measurement of final-state polarization. This contribution will report the current status of this program, with results from full-simulation studies of these processes in the detectors proposed for the ILC.
