Flavor independent search for hadronically decaying Higgs bosons

A searc h for the Higgs-strahlung pro cess was performed using events with four-jet top ology selected from 425 pb-1 of e+e- collision data, whic h were collected at p s ' 192 - 209 GeV by the OP AL detector at LEP . The searc h only mak es use of the kinematic signature of Higgs- strahlung events, and thus, is sensitiv e to all events in which the Higgs boson h 0 decays into quark pairs of arbitrary avour or into gluon pairs. In con trast to searches for the Standard Model Higgs boson, which are sensitive only to h0 -> bb (and h0 -> T+T-), this search remains sensitive in models, such as Two-Higgs-Doublet-models, in which the branching ratio into b quarks is suppressed for certain mo del parameters. The result is com bined with analyses of other event top ologies and previous results using data collected at p s = 189 GeV and 91 GeV . (not complete)
