Spins in Gluino Decays

Abstract

To unambiguously claim that we see a gluino at the LHC we need to prove its fermionic nature. Looking only at angular correlations we can distinguish a universal extra dimensional interpretation of a gluino cascade decay (assuming a bosonic heavy gluon) from supersymmetry. In addition to the known lepton--hadron asymmetries we also use of purely hadronic correlations in the gluino--sbottom decay chain.
