Search for WW decay of a Higgs boson produced in association with a fermion pair in e+e- collisions at LEP

Sumario:A search for WW decay of a Higgs boson produced in association with a fermion pair via the Higgs-strahlung or boson-fusion diagram is performed with the data collected by the ALEPH detector in years 1999 and 2000. This corresponds to an integrated luminosity of 453.3 pb-1 at center-of-mass energies ranging from 191 to 209 GeV. Thirteen exclusive selections are developed according to the different final state topologies. An upper limit is derived, as a function of the Higgs boson mass, on the product of the e+e to Hff and the H to WW branching ratio.
