摘要：

At root s = 7 TeV, the standard model (SM) needs at least 10 (fb)(-1) integrated luminosity at LHC to make a definitive discovery of the Higgs boson. Using binary tetrahedral (T') discrete flavor symmetry, we discuss how the decay of the lightest T' Higgs into gamma gamma can be effectively enhanced and dominate over its decay into b (b) over bar. 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 similar to 1 (fb)(-1).
