It is a gluino

Abstract
For a long time it has been known that the like-sign dilepton signature can help establish the existence of a gluino at the LHC. To unambiguously claim that we see a strongly interacting Majorana fermion—which we could call a gluino—we need to prove that it is indeed a fermion. We propose how to extract this information from a different gluino-decay cascade which is also used to measure its mass. Looking only at angular correlations we distinguish a universal extra dimensional interpretation assuming a bosonic heavy gluon from supersymmetry with a fermionic gluino. Assuming a supersymmetric interpretation, we show how the same angular correlations can be used to study the left-right nature of the sfermions appearing in the decay chain.
