Title: Compressed supersymmetry after 1 fb⁻¹ at the Large Hadron Collider

We study the reach of the Large Hadron Collider with 1 fb⁻¹ of data at √s=7 TeV for several classes of supersymmetric models with compressed mass spectra, using jets and missing transverse energy cuts like those employed by ATLAS for summer 2011 data. In the limit of extreme compression, the best limits come from signal regions that do not require more than 2 or 3 jets and that remove backgrounds by requiring more missing energy rather than a higher effective mass.
