| Abstract | ATLAS presents three searches for resonances decaying to top anti-top quark pairs performed on 7 \tev{} proton - proton collisions collected by the ATLAS detector at the Large Hadron Collider (LHC). No significant excess of events is observed over the Standard Model expectations. Tight constraints are derived on the production rate of $t \bar{t}$ resonances, leading to exclusion at 95 % C.L. of the mass range [0.5 \tev{}, 1.1 \tev{}] for a leptophobic Z' and [0.5 \tev{}, 1.5 \gev{}] for a Kaluza Klein excitation of the gluon. |
