Abstract

We discuss the SM Higgs discovery potential of LHC in the reaction $pp \to H + j e t \to γ γ + j e t$ when the jet is observed at sufficiently high $E_{t}$ to be reliably identified. We conclude that this channel gives promising discovery possibilities for the Higgs boson mass range 100-140 GeV, during LHC operation at a low luminosity. With 30 fb $^{- 1}$ of accumulated data and for $M_{H} = 120$ GeV about 100 signal events could be observed with the number of background events larger by a factor of 2 only, showing a signal significance $S / B \sim 7$ . We use the difference of distributions in the partonic subprocess energy $s^$ for the signal and background for a better separation of the signal.
