LHC Higgs Production and Decay in the T' Model

Abstract

At $\sqrt{s}=7$ TeV, the standard model needs at least $10(fb{)}^{-1}$ integrated luminosity at LHC to make a definitive discovery of the Higgs boson. Using binary tetrahedral ($T^{{}^{\prime }}$) discrete flavor symmetry, we discuss how the decay of the lightest $T^{\prime }$ Higgs into $\gamma \gamma$ can be effectively enhanced and dominate over its decay into $b\bar{b}$. Since the two-photon final state allows for a clean reconstruction, a decisive Higgs discovery may be possible at 7 TeV with the integrated luminosity only of $\sim 1(fb{)}^{-1}$.
