Gluino pair production close to threshold — •Matthias Kauth, Johann H. Kühn, Peter Marquard, and Matthias Steinhauser — Karlsruher Institut für Technologie

Supersymmetry (SUSY) is one of the most promising candidates for physics beyond the Standard Model. If SUSY exists and if it appears at the TeV scale, we will observe pair production of gluinos at the LHC. Although the production cross section, including higher oder corrections, is known, binding effects between the two particles have to be included into the analysis of hadroproduction. Attractive colour representations for the bound states of two gluinos enhance the cross section in particular below threshold if the decay rate of a single gluino is smaller than the level spacing between the resonance peaks. Next-to-leading order corrections for the various subprocesses are presented in analytic form together with numerical results for the production cross sections.
