Naturally split supersymmetry

TL;DR

This paper explores a paradigm shift in supersymmetric model building driven by experimental constraints, demonstrating that a naturally hierarchical spectrum can emerge from brane-world induced supersymmetry breaking.

Contribution

First detailed numerical study of brane-world induced supersymmetry breaking in minimal and next-to-minimal models showing natural hierarchy emergence.

Findings

Hierarchical spectrum emerges from bulk and brane-localized fields

Results relevant for future LHC phases

Supports paradigm shift in supersymmetry models

Abstract

Nonobservation of superparticles till date, new Higgs mass limits from the CMS and ATLAS experiments, WMAP constraints on relic density, various other low energy data, and the naturalness consideration, all considered simultaneously imply a paradigm shift of supersymmetric model building. In this paper we perform, for the first time, a detailed numerical study of brane-world induced supersymmetry breaking for both minimal and next-to-minimal scenarios. We observe that a naturally hierarchical spectrum emerges through an interplay of bulk, brane-localized and quasi-localized fields, which can gain more relevance in the subsequent phases of the LHC run.
