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 \underline{slopes} of a number of observable quantities in an energy region around 3 TeV are only dependent on $\tan\beta$. Under optimal experimental conditions, a combined measurement of slopes might identify $\tan\beta$ values in a range $\tan\beta< 2$, $\tan\beta>20$ with acceptable precision.
