Limits on metastable gluinos from ATLAS SUSY searches at 8 TeV

In some models of supersymmetry, the gluino is metastable and travels a measurabledistance in the detector before decaying to quarks (or a gluon) and a neutralino. Resultsof ATLAS SUSY searches designed for promptly decaying squarks and gluinos, producedat 8 TeV pp collisions at the Large Hadron Collider, are reinterpreted in the context ofmetastable gluinos. Limits are presented as a function of gluino mass, gluino lifetime, andneutralino mass. Decays of the gluino to t¯t ˜01are studied separately from decays to q¯q ˜01(where q is a non-top quark) or g ˜01. The gluino is excluded at 95% confidence level up tom˜g = 850 (900) GeV for decays to q¯q ˜01/ g ˜01(t¯t ˜01), for a lifetime of 1 ns and m˜01= 100 Ge
