In this thesis we concentrate on the determination of the spin of an intermediate particle by using a decay chain. In SUSY the gluino is especially interesting for searches at the LHC, since it is a Majorana fermion which can produce like-sign dileptons in the final state. In UED the like-sign dilepton signature could occur as well from the decay of a bosonic KK-gluon. As we will show, angular distributions of the outgoing b-jets in SUSY and UED differ due to the different coupling structures. The effect from the different boosts of gluino and heavy gluon is shown to be much smaller. The hadronic UED cross section for KK-gluon KK-quark collisions is calculated in leading order and compared to the gluino squark collision in SUSY. The analytically given partonic cross sections are compared at the threshold.
