TL;DR

This paper introduces a class of folded supersymmetry models with a twist in boundary conditions that stabilize the weak scale, fit the Higgs data, and predict unique collider signatures, remaining viable under current LHC constraints.

Contribution

It presents a new calculable framework for folded supersymmetry with boundary condition twists, compatible with observed Higgs properties and LHC data.

Findings

Models can reproduce observed Higgs mass and couplings.

Models remain minimally fine-tuned with current LHC data.

Predicts distinctive collider signatures for future searches.

Abstract

Folded supersymmetry (f-SUSY) stabilizes the weak scale against radiative corrections from the top sector via scalar partners whose gauge quantum numbers differ from their Standard Model counterparts. This non-trivial pairing of states can be realized in extra-dimensional theories with appropriate supersymmetry-breaking boundary conditions. We present a class of calculable f-SUSY models that are parametrized by a non-trivial twist in 5D boundary conditions and can accommodate the observed Higgs mass and couplings. Although the distinctive phenomenology associated with the novel folded states should provide strong evidence for this mechanism, the most stringent constraints are currently placed by conventional supersymmetry searches. These models remain minimally fine-tuned in light of LHC8 data and provide a range of both standard and exotic signatures accessible at LHC13.
