The Right-Handed Slepton Bulk Region for Dark Matter in Generalized No-scale $\mathcal{F}$-$SU(5)$ with Effective Super-Natural Supersymmetry

TL;DR

This paper introduces a simplified supergravity framework that naturally addresses fine-tuning and dark matter, highlighting a specific slepton region that could be tested by future experiments beyond current collider capabilities.

Contribution

It presents a new generalized no-scale supergravity model within $ ext{F}$-$ ext{SU}(5)$ that naturally incorporates dark matter and predicts a testable slepton bulk region.

Findings

Identifies a light right-handed slepton bulk region in $ ext{F}$-$ ext{SU}(5)$ and pMSSM.

Suggests this region may be beyond LHC reach but accessible to future experiments.

Proposes a natural solution to the electroweak fine-tuning problem.

Abstract

We propose Generalized No-Scale Supergravity, the simplest scenario for Effective Super-Natural Supersymmetry, naturally solving the supersymmetry electroweak fine-tuning problem and including natural dark matter. A light right-handed slepton bulk region is realized in $\mathcal{F}$-$SU(5)$ and the pMSSM. The bulk may be beyond the LHC reach, though can be probed at the 1000-day LUX-ZEPLIN, Future Circular Collider (FCC-ee) at CERN, Circular Electron Positron Collider (CEPC), and Hyper-Kamiokande.
