More Visible Effects of the Hidden Sector

TL;DR

This paper explores how strong, superconformal hidden sector dynamics influence supersymmetry breaking parameters, revealing effects like suppressed gaugino masses and novel superparticle spectra, with implications for various mediation mechanisms.

Contribution

It uncovers previously unrecognized effects of hidden sector dynamics on supersymmetry breaking, including gaugino mass suppression and unique superparticle spectra.

Findings

Gaugino masses are suppressed relative to the gravitino mass.

Hidden sector effects impact anomaly, gauge, and gaugino mediation.

New superparticle mass spectra are proposed.

Abstract

There is a growing appreciation that hidden sector dynamics may affect the supersymmetry breaking parameters in the visible sector (supersymmetric standard model), especially when the dynamics is strong and superconformal. We point out that there are effects that have not been previously discussed in the literature. For example, the gaugino masses are suppressed relative to the gravitino mass. We discuss their implications in the context of various mediation mechanisms. The issues discussed include anomaly mediation with singlets, the mu (B mu) problem in gauge and gaugino mediation, and distinct mass spectra for the superparticles that have not been previously considered.
