A search for neutral Higgs bosons decaying to pairs of τ leptons with the ATLAS detector at the LHCis presented. The analysis is based on proton–proton collisions at a center-of-mass energy of 7 TeV,recorded in 2010 and corresponding to an integrated luminosity of 36 pb−1 . After signal selection, 276events are observed in this data sample. The observed number of events is consistent with the totalexpected background of 269 ± 36 events. Exclusion limits at the 95% confidence level are derived for theproduction cross section of a generic Higgs boson φ as a function of the Higgs boson mass and for A / H /hproduction in the Minimal Supersymmetric Standard Model (MSSM) as a function of the parameters m Aand tan β .
