A Monte Carlo simulation for the supersymmetric (SUSY) processes e/sup +/e/sup -/..-->..FTHETA..-->..gg-tildeg-tilde and gg-italic-tildegamma-tilde, where FTHETA is a tt-bar bound state, has been carried out to a fully hadronized final state. In the search for a unique signature, a detailed comparison to the non-SUSY processes e/sup +/e/sup -/..-->..FTHETA..-->..ggg and gg..gamma.. was performed, in both jet analysis and the shape of the events. We found that in the SUSY modes the missing energy is very large compared to the non-SUSY ones. The jet spectrum of the two modes is quite different and is related to the jet's origin. The SUSY modes have many more four- and five-jet events. The number of B mesons and neutrinos is also enhanced in the SUSY mode. The study included dependence on the masses of the top quark and the g-italic-tilde. A method to determine the g-italic-tilde 's mass, using the missing-energy distribution, has been developed.
