Searches for Exotics physics states in jets and boosted objects final states at ATLAS

We present searches for new particles decaying to jets and boosted objects final states using data collected in 7 TeV LHC proton-proton collisions with the ATLAS detector. We present studies of events characterized by the presence of dijets or of photons and jets or of monojet, $tar{t}$ resonances and 4th generation particles decaying hadronically. These studies demonstrate the usage of novel techniques for the reconstruction of boosted objects and test A wide set of predictions for Exotics extensions to Standard Model.
