Search for new Physics using Jets at ATLAS

Studies of high energy jets at the Large Hadron Collider is one of the most direct way to search for physics beyond the Standard Model. Often the backgrounds from the Standard Model processes are quite large, and therefore a good understanding of the jet performance associated with the use of data-driven methods are crucial for achieving a good sensitivity. This conference report presents a compilation of the latest results on the Exotics searches in ATLAS involving a jet plus anything else in the final state based on the analysis of the 2011 and 2012 pp collision data collected with the ATLAS detector at a center-of-mass energy of 7 TeV and 8 TeV respectively. We summarize namely the analyses of the monojets, dijets and multijets final states where the data are confronted with the Standard Model predictions. The results are interpreted in the context of various models Beyond the Standard Model: dark matter, light gravitino production, contact interactions and gravitationally mediated effects in large extra dimensions, excited quarks, quatum black hole productions and lepto-quark production.
