Abstract

We examine the prospects for measuring the photon-photon branching ratio of a Standard-Model-like Higgs boson ( $h$ ) at the Next Linear $e^+e^-$ Collider when the Higgs boson is produced via $W^+W^-$ --fusion: $e^+e^-\to\nu_e \bar\nu_e h$ . In particular, we study the accuracy of such a measurement and the statistical significance of the associated signal as a function of the electromagnetic calorimeter resolution and the Higgs boson mass. We compare results for the $W^+W^-$ --fusion production/measurement mode with the results obtained for the $e^+e^-\rightarrow Z^*\rightarrow Z h$ production/measurement mode in a parallel earlier study.
