| Abstract: | The third-order supersymmetric QCD contribution to the high-energy hadronic production of gluino-gluino bound states is calculated. Several experimental cuts are proposed in order to increase the signal-to-background ratio. This ratio is shown to be 2 to 3 times larger in three-jet events than in two-jet events, reaching 5–7%. This gain in efficiency could be crucial in the case of limited statistics and an experimental two-jet mass resolution of a few GeV. |
