A search for high-mass resonances decaying to τ + τ − in pp collisions at √s=7 TeV with the ATLAS detector

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 signifi...
