Sheffield has extensive involvement in a number of Supersymmetry analyses within ATLAS. We developed the Jet Smearing technique which to date has been used for QCD background estimation in the main 0-lepton search channel, the 0-lepton with b-jets search, one of the stop squark searches and as a cross-check in the 0-lepton multijet analysis. An official tool has recenrly been developed, and details of this are found here .

As well as jet smearing in general the Sheffield group participates in the 0-lepton analysis, 0-lepton with b-jets and stop pair searches. Public SUSY results may be found here
