(De)Constructing a Natural and Flavorful Supersymmetric Standard Model

TL;DR

This paper constructs supersymmetric models using deconstruction that naturally explain flavor hierarchies, produce a realistic superpartner spectrum, and address electroweak symmetry breaking without fine-tuning.

Contribution

It introduces a novel deconstructed framework for supersymmetry that naturally generates flavor hierarchies and a realistic superpartner spectrum.

Findings

Electroweak symmetry breaking is fully natural.

The models produce a flavorful soft spectrum compatible with precision limits.

The Higgs mass can be raised above LEP bounds without large radiative corrections.

Abstract

Using the framework of deconstruction, we construct simple, weakly-coupled supersymmetric models that explain the Standard Model flavor hierarchy and produce a flavorful soft spectrum compatible with precision limits. Electroweak symmetry breaking is fully natural; the mu-term is dynamically generated with no B mu-problem and the Higgs mass is easily raised above LEP limits without reliance on large radiative corrections. These models possess the distinctive spectrum of superpartners characteristic of "effective supersymmetry": the third generation superpartners tend to be light, while the rest of the scalars are heavy.
