Partially Supersymmetric Composite Higgs Models

TL;DR

This paper explores a model where the Higgs boson is a pseudo-Goldstone boson within a partially supersymmetric framework, potentially raising the compositeness scale and addressing flavor and precision measurement constraints.

Contribution

It introduces a novel partially supersymmetric composite Higgs model within Randall-Sundrum scenarios and their CFT duals, combining supersymmetry with composite Higgs ideas.

Findings

Supersymmetry in the strong sector allows raising the compositeness scale to ~10 TeV.

The model naturally solves the supersymmetric flavor problem.

At low energies, reduces to a minimal SUSY-like model accessible at the LHC.

Abstract

We study the idea of the Higgs as a pseudo-Goldstone boson within the framework of partial supersymmetry in Randall-Sundrum scenarios and their CFT duals. The Higgs and third generation of the MSSM are composites arising from a strongly coupled supersymmetric CFT with global symmetry SO(5) spontaneously broken to SO(4), whilst the light generations and gauge fields are elementary degrees of freedom whose couplings to the strong sector explicitly break the global symmetry as well as supersymmetry. The presence of supersymmetry in the strong sector may allow the compositeness scale to be raised to ~10 TeV without fine tuning, consistent with the bounds from precision electro-weak measurements and flavour physics. The supersymmetric flavour problem is also solved. At low energies, this scenario reduces to the "More Minimal Supersymmetric Standard Model" where only stops, Higgsinos and gauginos are light and within reach of the LHC.
