Search for Highly Collimated Top Quarks with the ATLAS Detector

A search for the production of top quarks with high transverse momentum (pt \textgreater\ 750 GeV) in pp collisions has been performed at ATLAS. Top quarks decaying to all hadronic final states are reconstructed in single collimated jets. A complementary cone method is used to mediate the effects of multiple pp collisions during high luminosity data taking. The measured cross-section is compared to Standard Model predictions.
