SUSY searches in early ATLAS data

We review the SUSY searches strategy that will be adopted at the ATLAS startup. The Large Hadron Collider will deliver proton proton collisions at an unprecedented centre of mass energy of 14TeV, making it possible to expand the searches for SUSY well beyond the limit set by the present experiments at the Tevatron collider. Discovering SUSY may be possible using data accumulated during the first few months of running, but it will mostly depend on our ability to understand the experimental systematics, and to estimate the Standard Model background. The discovery reach for the first fb^-1 of data collected by ATLAS is given for the case where the mSUGRA model is realised.
