Itʼs on: Early interpretations of ATLAS results in jets and missing energy searches

The first search for supersymmetry from ATLAS with 70 nb−1 of integrated luminosity extends the Tevatronʼ s reach for colored particles that decay into jets plus missing transverse energy. For gluinos that decay directly or through a one step cascade into the LSP and two jets, the mass range mg˜⩽205 GeV is disfavored by the ATLAS searches, regardless of the mass of the LSP. In some cases the coverage extends up to mg˜≃295 GeV, already surpassing the Tevatronʼs reach for compressed supersymmetry spectra.
