Prospects for the observation of a Higgs boson with H → τ+τ- → l+l-pt associated with one high-PT jet at the LHC

We investigate the sensitivity of the LHC experiments to the Standard Model Higgs using H -> tau tau -> l(+)l(-) p(t) associated with one high-P-T jet in the mass range 110 < M-H < 150 GeV/c(2). Cut and Neural Network based event selections are chosen to optimize the expected signal significance with this decay mode. A signal significance of about 6.2 sigma can be achieved for M-H = 120 GeV/c(2) with 30 fb(-1) of integrated luminosity for one experiment only. Additionally, experimental issues related to tagging forward jets, reconstructing missing transverse momentum and the application of a central jet veto are simplified considerably.
