EXOTIC PHYSICS SEARCHES WITH THE ATLAS DETECTOR

A selection of the most recent ATLAS results of searches for new physics phenomena are detailed. The proton-proton collision data were collected up to the first half of 2011 with the ATLAS detector at 7 TeV centre-of-mass energy produced by the LHC. Summaries are given of leptonic search signatures, of dilepton resonances, and of a charged lepton and neutrino, interpreted in the context of heavy gauge bosons and Randall-Sundrum gravitons. A search for monojet final states is detailed, and limits placed on large extra-dimensional models. The most recent ATLAS results for dijet resonances are described. Two other search results are outlined: a study of the dijet invariant mass in events with an associated W boson, and a search for first or second generation scalar leptoquarks.
