| dc.description | One way to suppress flavor changing neutral currents or CP violating processes in supersymmetry is to make at least some of the first two generations' scalars superheavy (above ~20 TeV). We summarize the motivations and challenges, theoretically and phenomenologically, for superheavy supersymmetry. We then argue for more viable alternatives on the superheavy theme and are led to models where the heavy spectrum follows a pattern of masses similar to what arises from gauge-mediation or with a "hybrid" spectrum of light and heavy masses based on each particle's transformation under a global SU(5). In the end, despite the differences between the competing ideas, a self-consistent natural theory with superheavy masses seems to prefer low-energy supersymmetry breaking with possible correlations among the light sparticle masses. The resulting light gravitino and its couplings to matter could also impact the discovery capabilities and analyses of these models at colliders. In addition, we comment on how the presence of superheavy states may influence the light spectrum, and how this may help efforts to distinguish between theories post-discovery. | |
