Jf. Gunion et Pc. Martin, PROSPECTS FOR AND IMPLICATIONS OF MEASURING THE HIGGS-BOSON TO PHOTON-PHOTON BRANCHING RATIO AT THE NEXT LINEAR E(-)-COLLIDER()E(), Physical review letters, 78(24), 1997, pp. 4541-4544
We evaluate the prospects for measuring B(h --> gamma gamma) for a sta
ndard-model-like Higgs boson at the Next Linear e(+)e(-) Collider in t
he e(+)e(-) --> Z --> Zh and e(+)e(-) --> nu(e)<(nu)over bar>(e)h pro
duction modes. Relative merits of different machine energy/luminosity
strategies and different electromagnetic calorimeter designs are evalu
ated. We emphasize the importance of measuring B(h --> gamma gamma) in
order to obtain the total width of a light Higgs boson and thereby th
e <(b)over bar b> partial width that will be critical in discriminatin
g between the standard model Higgs boson and the Higgs boson of an ext
ended model.
