Top Quark Production at TeV Energies as a Potential SUSY Detector ∗

We consider the process of top-antitop production from electron-positron annihilation, for c. m. energies in the few TeV regime, in the MSSM theoretical framework. We show that, at the one loop level, the slopes of a number of observable quantities in an energy region around 3 TeV are only dependent on tan β. Under optimal experimental conditions, a combined measurement of slopes might identify tan β values in a range tan β < 2, tan β > 20 with acceptable precision.
