The Experimental Investigation of Supersymmetry Breaking

If Nature is supersymmetric at the weak interaction scale, what can we hopeto learn from experiments on supersymmetric particles? The most mysteriousaspect of phenomenological supersymmetry is the mechanism of spontaneoussupersymmetry breaking. This mechanism ties the observable pattern ofsupersymmetric particle masses to aspects of the underlying unified theory atvery small distance scales. In this article, I will discuss a systematicexperimental program to determine the mechanism of supersymmetry breaking. Both$pp$ and $e^+e^-$ colliders of the next generation play an essential role.[Lecture presented at the 1995 Yukawa International Symposium (YKIS`95), toappear in the proceedings.]Comment: 33 pages, latex + 16 figure
