Description
I will present results of a search for the 125 GeV Higgs boson decaying to a pair of tau leptons. The dataset used is 20.3fb$^{-1}$ of proton-proton collision recorded by the ATLAS detector at a centre of mass energy of 8 TeV. The observed (expected) deviation from the background only hypothesis corresponds to a significance of 4.1 (3.2) standard deviations. The measured signal strength is $\mu = 1.4^{+0.5}_{-0.4}$.
This constitutes evidence for the existence of Higgs to $\tau\tau$ decays and is consistent with the Standard Model expectation of a Higgs Boson with mass 125 GeV.
