Search for the standard model Higgs boson in the H to τ⁺ τ^- to lepton-hadron and hadron-hadron decay modes with the ATLAS Detector

In this proceeding, a search for a Higgs boson in the H to τ⁺ τ^- decay mode, where both taus decay hadronically or one decay hadronically and one leptonically. The analysis is based on a data sample of proton-proton collision collected by the ATLAS detector at the Large Hadron Collider (LHC) at centre-of-mass energies of 7 TeV during 2011, corresponding to an integrated luminosity of 4.7 f b^-1. No significant excess is observed in the Higgs boson mass range of 100-150 GeV. The observed (expected) limits on the cross-section times branching ratio for H to τ⁺ τ^- at m_H = 125 GeV are 6.2(5.9) and 6.3(6.5) for lepton-hadron and hadron-hadron decay modes, respectively.
