Electroweak Naturalness and Deflected Mirage Mediation

TL;DR

This paper explores electroweak naturalness in deflected mirage mediation models of supersymmetry, finding regions with low fine-tuning comparable to the phenomenological MSSM, which are testable at the LHC.

Contribution

It demonstrates that deflected mirage mediation models can achieve low electroweak fine-tuning similar to the pMSSM, expanding the viable parameter space for natural supersymmetry.

Findings

Low electroweak fine-tuning regions identified in DMM models.

DMM models' parameter space overlaps with pMSSM.

Testable predictions for LHC experiments.

Abstract

We investigate the question of electroweak naturalness within the deflected mirage mediation (DMM) framework for supersymmetry breaking in the minimal supersymmetric standard model (MSSM). The class of DMM models considered are nine-parameter theories that fall within the general classification of the 19-parameter phenomenological MSSM (pMSSM). Our results show that these DMM models have regions of parameter space with very low electroweak fine-tuning, at levels comparable to the pMSSM. These parameter regions should be probed extensively in the current LHC run.
