Abstract

A method using jets is investigated for detecting the Higgs boson at LHC in the mass range about 114 GeV/c^2, suggested by LEP experiments. Higgs bosons are produced in association with a tt̄ pair, and both t and t̄ decay semileptonically to reduce the QCD background. After appropriate cuts, the signal is compared with the main background, tt̄ + 2 jets. This estimate, using a reasonable approximation for the dominant background tt̄gg, suggests a 5.1σ effect. This method is seen to be complimentary to the two gamma signal. The tt̄Z channel, with Z decaying to l^+ l^−, may be used to reduce theoretical uncertainties in determining the tt̄H signal.
