[SLAC] [SLAC Pubs and Reports] SLAC-PUB-7633Chi2 Analysis of Supersymmetric Models Abstract We discuss the results of a global fit to precision data in supersymmetric models. We consider both gravity- and gauge-mediated models. As the superpartner spectrum becomes light, the global fit to the data typically results in larger values of $\chi^2$. We indicate the regions of parameter space which are excluded by the data. We discuss the additional effect of the $B(B\rightarrow X_s\gamma)$ measurement. Our analysis excludes chargino masses below $M_Z$ in the simplest gauge-mediated model with $\mu>0$, with stronger constraints for larger values of $\tan\beta$. (Equations render on Windows, Mac OS, AIX, Linux, Solaris, and IRIX with the techexplorer plug-in.)
