Resumen:
This Letter presents a search for high-mass resonances decaying into @t^+@t^- 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 @t^+@t^- 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.This Letter presents a search for high-mass resonances decaying into tau+tau- final states using proton-proton collisions at sqrt(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 inverse femtobarns. 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 tau+tau- 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.
