Search for Higgs bosons decaying to WW in e+e- collisions at LEP
(2007)The European Physical Journal CA search for Higgs bosons produced in association with a fermion pair, and decaying to WW, is performed with the data collected by the ALEPH detector at centre-of-mass energies ranging from 191 to 209 GeV. The data correspond to an integrated luminosity of 453.2 pb-1. Thirteen exclusive selections are developed according to the different final state topologies. No statistically significant evidence for a Higgs boson decaying into a WW ...Journal Article -
Fermion pair production in e+e- collisions at 189-209 GeV and constraints on physics beyond the standard model
(2007)The European Physical Journal CCross sections, angular distributions and forward-backward asymmetries are presented, of two-fermion events produced in e+e- collisions at centre-of-mass energies from 189 to 209 GeV at LEP, measured with the ALEPH detector. Results for e+e-, μ+μ-, τ+τ-, qq̄, bb̄ and cc̄ production are in agreement with the standard model predictions. Constraints are set on scenarios of new physics such as four-fermion contact interactions, leptoquarks, ...Journal Article -

NNLO QCD predictions for the H → WW → ℓνℓν signal at the LHC
(2007)Journal of High Energy PhysicsWe present a first computation of the next-to-next-to-leading order (NNLO) QCD cross-section at the LHC for the production of four leptons from a Higgs boson decaying into W bosons. We study the cross-section for a mass value of Mh ≤ 165GeV; around this value a Standard Model Higgs boson decays almost exclusively into W-pairs. We apply all nominal experimental cuts on the final state leptons and the associated jet activity and study the ...Journal Article -
