Searches for physics beyond the Standard Model at ATLAS

Results on searches for new phenomena in particle physics are presented using p-p collision data collected with the ATLAS detector at the Large Hadron Collider at CERN. The data correspond to an integrated luminosity ranging from 31 to 236pb−1 and have been collected during 2010 and up to May 2011. No signal of new phenomena was observed and limits were placed on the parameter space of various theoretical frameworks, e.g. supersymmetry and extra dimensions.
