WHAT IS THE SCALE OF SUPERSYMMETRY BREAKING

For a long time, it has been widely assumed that if the underlying law s of nature are supersymmetric, supersymmetry is broken at a scale int ermediate between the weak scale and the Planck mass. The construction of realistic models of dynamical supersymmetry breaking in which supe rsymmetry is broken at a much lower scale, as well as a growing apprec iation of the supersymmetric flavor problem has reopened this question . After reviewing some ideas for understanding the microscopic origin of the soft breaking parameters in the context of string theory, I tur n to low energy breaking. Independent of the details of the underlying theory, events with photons and missing energy, like the CDF e(+)e(-) gamma gamma/E(T) event, are Likely signals of low energy breaking. I b riefly review the predictions of the simplest model of low energy supe rsymmetry breaking for the soft breaking parameters (MGM), and then as k what sorts of generalizations are possible. It turns out that if all couplings are weak, there are only a limited number of ways to modify the model.
