Minimal Yukawa-Gauge Mediation

TL;DR

This paper explores a supersymmetry breaking mechanism combining Yukawa and gauge interactions, resulting in a unique MSSM spectrum with heavy higgsinos and inverted sfermion hierarchy, aligning with recent LHC findings.

Contribution

It introduces a novel Yukawa-Gauge mediation framework that produces distinctive MSSM spectra with specific phenomenological features.

Findings

MSSM spectrum resembles split SUSY with heavy higgsinos

Features an inverted hierarchy of sfermion masses

Predictions are consistent with recent LHC searches

Abstract

We consider a scenario in which Supersymmetry breaking is communicated to the MSSM fields through the interplay of yukawa and gauge interactions. The MSSM spectrum resembles that of split SUSY scenarios, but on top of that it develops some peculiar features like heavy higgsinos and an inverted hierarchy of sfermion masses. The predictions obtained are consistent with the most recent LHC SUSY and Higgs boson searches.
