Abstract

This Letter presents a search for high-mass resonances decaying into τ⁺τ⁻ final states using proton-proton collisions at s=7 TeV produced by the Large Hadron Collider. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 4.6 fb⁻¹. No statistically significant excess above the Standard Model expectation is observed; 95% credibility upper limits are set on the cross section times branching fraction of Z^′ resonances decaying into τ⁺τ⁻ pairs as a function of the resonance mass. As a result, Z^′ bosons of the Sequential Standard Model with masses less than 1.40 TeV are excluded at 95% credibility.
