Abstract
A measurement of the tt production cross section in the all-hadronic decay mode is presented using 4.7 fb-1 of proton-proton collisions at a centre of mass energy of 7 TeV collected by the ATLAS experiment in 2011. Events are selected using a multi-jet trigger. Kinematic and b-tagging requirements are then applied to identify tt event candidates. A kinematic fit reconstructs the event topology of the final state extracting the top-quark mass which is then used to measure the production cross section with an unbinned likelihood fit. The result is found in good agreement with the Standard Model prediction for a top-quark mass of 172.5 GeV.
