The potential for the discovery of a Standard Model Higgs boson in the mass range m(H) < 2m(Z) in the vector boson fusion mode has been studied for the ATLAS experiment at the LHC. The characteristic signatures of additional jets in the forward regions of the detector and of low jet activity in the central region allow for an efficient background rejection. Analyses for the H -> WW(()*()) and H -> tau tau decay modes have been performed using a realistic simulation of the expected detector performance. The results obtained demonstrate the large discovery potential in the H -> WW(()*()) decay channel and the sensitivity to Higgs boson decays into tau-pairs in the low-mass region around 120 GeV/c(2).

Abstract
The potential for the discovery of a Standard Model Higgs boson in the mass range m(H) < 2m(Z) in the vector boson fusion mode has been studied for the ATLAS experiment at the LHC. The characteristic signatures of additional jets in the forward regions of the detector and of low jet activity in the central region allow for an efficient background rejection. Analyses for the H -> WW(()*()) and H -> tau tau decay modes have been performed using a realistic simulation of the expected detector performance. The results obtained demonstrate the large discovery potential in the H -> WW(()*()) decay channel and the sensitivity to Higgs boson decays into tau-pairs in the low-mass region around 120 GeV/c(2).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
