Prospects for Supersymmetry discovery based on inclusive searches in ATLAS

This document summarizes the studies performed by ATLAS to address the Supersymmetry discovery based on inclusive searches, assuming 1 fb-1 of data and 14 TeV center-of-mass energy. The final states consisting on large missing transverse energy and multiple high energy jets were considered in different searching channels, depending on the presence of leptons or objects from the third generation in the decay chains. The 5sigma discovery potential of the searches was addressed in different supersymmetric models, including an estimation of the systematic uncertainties.
