The searches of final states involving top quarks are one of the most promising way to observe deviation from the Standard Model (SM). Some beyond of the SM theories predict the existence of new particles that are strongly coupled to the top quark, because of its high mass. A particular attention will be devoted to searches for ttbar resonances in the lepton plus jets final states performed with the ATLAS experiment at the LHC. The search will use early 2011 data sample, recorded at a proton-proton centre-of-mass energy of 7 TeV. Using the reconstructed ttbar mass spectrum, we expect to set limits on the mass of the new particle predicted by narrow Z' and Kaluza-Klein (KK) gluon models.
