Natural generalized mirage mediation
Howard Baer, Vernon Barger, Hasan Serce, Xerxes Tata

TL;DR
This paper introduces a generalized version of mirage mediation in supersymmetry, allowing continuous parameters to better align with experimental constraints and potentially evade current collider detection limits.
Contribution
It broadens the mirage mediation framework to include continuous parameters, enabling natural SUSY spectra consistent with Higgs and LHC bounds, and discusses detection prospects.
Findings
Natural SUSY spectra are achievable within GMM.
Some models may be beyond high-luminosity LHC reach.
ILC could be essential for discovering higgsino-like WIMPs.
Abstract
In the supersymmetric scenario known as mirage mediation (MM), the soft SUSY breaking terms receive comparable anomaly-mediation and moduli-mediation contributions leading to the phenomenon of mirage unification. The simplest MM SUSY breaking models which are consistent with the measured Higgs mass and sparticle mass constraints are strongly disfavoured by fine-tuning considerations. However, while MM makes robust predictions for gaugino masses, the scalar sector is quite sensitive to specific mechanisms for moduli stabilization and potential uplifting. We suggest here a broader setup of generalized mirage mediation (GMM), where heretofore discrete parameters are allowed as continuous to better parametrize these other schemes. We find that natural SUSY spectra consistent with both the measured value of m(h). as well as LHC lower bounds on superpartner masses are then possible. We…
