A search for high-mass resonances decaying into τ+τ− final states using proton-proton collisions at √s = 8 TeV produced by the Large Hadron Collider is presented. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 19.5–20.3 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 2.02 TeV are
excluded at 95% credibility. The impact of the fermionic couplings on the Z' acceptance
is investigated and limits are also placed on a Z' model that exhibits enhanced couplings
to third-generation fermions
