### Description

Several Beyond the Standard Model (BSM) theories predict the existence of new resonances that decay into ttbar pairs. We describe a search for such resonances using lepton plus jet data collected by the ATLAS experiment in pp collisions at Sqrt(s)=7 TeV. The selection criteria and search method are presented. In the absence of signal, we produce 95% CL limits on the production cross section times branching ratio of resonances predicted by a few such BSM models.
