SUMMARY:Supersymmetry without prejudice at the LHC - John Conley (Bonn)

DESCRIPTION:The discovery and exploration of Supersymmetry in a model-inde
 pendent fashion will be a daunting task due to the large number of soft-br
 eaking parameters in the MSSM. In this talk\, I describe an exploration of
  the capability of the ATLAS detector at the LHC to find SUSY within the 1
 9-dimensional pMSSM subspace of the MSSM using their standard transverse m
 issing energy and long-lived particle searches that were essentially desig
 ned for mSUGRA. To this end\, we made use of a set of 71k previously gener
 ated model points in the 19-dimensional parameter space that satisfy all o
 f the existing experimental and theoretical constraints. Employing ATLAS-g
 enerated SM backgrounds and following their approach in each of 11 missing
  energy analyses as closely as possible\, we explored all of these 71k mod
 el points for a possible SUSY signal.  I will describe the results of this
  analysis at both the 7 TeV and 14 TeV LHC.  I will touch on many differen
 t aspects of our results\, including the reasons why some models are misse
 d in all the analyses\, the effect of systematic error on the parameter sp
 ace coverage\, the impact of changing the analysis cuts\, fine-tuning in t
 he model set\, and implications for the linear collider.
