SUSY search with b jets at ATLAS

Inclusive SUSY search regard gluino and squark events which are characterised by multiple jets, leptons and missing transverse energy and can provide the first evidence of the deviation from the Standard Model. In this study signatures with b jets are analyzed for various SUSY benchmark points using the full GEANT4 detector simulation both for the signal events and for the Standard Model backgrounds. In the events with b jets isolated leptons may also be present, and all channels with and without leptons are summed. The results presented here are based on a total integrated luminosity of 0.1 fb^{-1} and 1fb^{-1} that may be collected during the first year of operation of the LHC.
