A search for high-mass ditau resonances decaying in the fully hadronic final state in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector

This note presents a search for high-mass ditau resonances decaying in the fully hadronic final state using proton-proton collisions at $\sqrt{s}= 8$ TeV produced by the Large Hadron Collider. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 19.5 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 $Z^{\prime}$ resonances decaying into $\tau^{+}\tau^{-}$ pairs as a function of the resonance mass. As a result, $Z^{\prime}$ bosons of the Sequential Standard Model with masses less than 1.90 TeV are excluded at 95% credibility.
