LHC Higgs Production and Decay in the T' Model

TL;DR

This paper explores how a $T'$ flavor symmetry model can enhance Higgs decay into two photons, potentially enabling earlier discovery at the LHC with less data than the standard model predicts.

Contribution

It introduces a $T'$ flavor symmetry framework that significantly boosts the Higgs decay into gamma gamma, improving detection prospects at the LHC.

Findings

Enhanced Higgs to gamma gamma decay in the $T'$ model

Potential for Higgs discovery at 7 TeV with only 1 fb$^{-1}$

Reduced luminosity requirement compared to the standard 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 ($T^{'}$) 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 $b \, \bar{b}$. 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 $\sim 1\, (fb)^{-1}$.
