Hildreth, M D

We describe methods one can employ at a [radical]s = 500 GeV e[sup +]e[sup [minus]] linear collider to measure the branching fractions of a Higgs boson. These methods select one Higgs decay mode above all others with high purity, leaving measureable Standard Model backgrounds as the only source of contamination. Integrated luminosities of 50fb[sup [minus]1] are required to obtain statistical errors of 10--20% on the branching fractions to b[bar b], [tau][sup +][tau][sup [minus]], and WW(*). For an intermediate mass Higgs this is sufficient to distinguish the MSSM from the Standard Model Higgs over most of the Supersymmetric parameter space.
