Gluino plus Squark Production Close to Threshold — •Achim Kreß, Johann H. Kühn, and Matthias Kauth — Karlsruher Institut für Technologie

The appearance of bound states modifies the cross section close to threshold for gluino plus squark production and even below. The hadronic production cross section of these bound states, as well as their strong and electroweak decay modes close to threshold are presented for various ``Snowmass Points''. Binding effects as well as the influcence of gluino and squark decy rates are taken into account. The calculations are based on the Green's Function formalism for a Coulomb like potential, which depends on the irreducible colour representation of the corresponding state. For the attractive representations, an enhancement of the cross section close to threshold is observed. Due to their multiplicity, the higher dimensional representations become dominant in the high energy region.
