Weak Scale Supersymmetry Without Weak Scale Supergravity

TL;DR

This paper proposes a framework where supersymmetry breaking occurs in the hidden sector, allowing gravitino and moduli masses to be much larger than 100 TeV, thus resolving cosmological issues associated with traditional models.

Contribution

It introduces a novel approach to supersymmetry breaking via anomaly mediation, compatible with unification and realizable in extra-dimensional or conformal field theory models.

Findings

Eliminates cosmological problems of hidden sector models.

Allows gravitino and moduli masses to exceed 100 TeV.

Compatible with gauge coupling unification.

Abstract

It is generally believed that weak scale supersymmetry implies weak scale supergravity, in the sense that the masses of the gravitino and gravitationally coupled moduli have masses below 100 TeV. This paper presents a realistic framework for supersymmetry breaking in the hidden sector in which the masses of the gravitino and gravitational moduli can be much larger. This cleanly eliminates the cosmological problems of hidden sector models. Supersymmetry breaking is communicated to the visible sector by anomaly-mediated supersymmetry breaking. The framework is compatible with perturbative gauge coupling unification, and can be realized either in models of "warped" extra dimensions, or in strongly-coupled four-dimensional conformal field theories.
