We examine the prospects for measuring the photon-photon branching ratio of a
Standard-Model-like Higgs boson (h) at the Next Linear e+eβ Collider when
the Higgs boson is produced via W+Wβ--fusion: e+eββΞ½eβΞ½Λeβh.
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+Wβ--fusion production/measurement mode with the results obtained for the
e+eββZββZh production/measurement mode in a
parallel earlier study.Comment: 5 pages, full postscript file also available via anonymous ftp at
