A flavour-independent Higgs boson search in e(+)e(-) collisions at root s up to 209 GeV

Primary tabs

Delaere, Christophe [UCL] Lemaitre, Vincent [UCL]

A search for the Higgsstrahlung process e(+)e(-) --> HZ is carried out, covering decays of the Higgs boson into any quark pair, a gluon pair or a tau pair. The analysis is based on the 630 pb(-1) of data collected by the ALEPH detector at LEP at centre-of-mass energies from 189 to 209 GeV. A 95% C.L. lower mass limit of 109.1 GeV/c(2) is obtained for a Higgs boson cross section equal to that expected from the Standard Model if the Higgs boson decays exclusively into hadrons and/or taus, irrespective of the relative branching fractions.
