Parameter Space of General Gauge Mediation

TL;DR

This paper explores a subset of General Gauge Mediation models, revealing diverse superpartner spectra and identifying common NLSP types beyond traditional gauge mediation predictions.

Contribution

It introduces a specific subspace of GGM models that produce a wider variety of superpartner spectra, including chargino and sneutrino NLSPs, expanding the understanding of gauge mediation phenomenology.

Findings

GGM models can produce diverse superpartner spectra.

Chargino and sneutrino NLSPs are common in GGM.

Traditional neutralino or stau NLSPs are easily reproduced.

Abstract

We study a subspace of General Gauge Mediation (GGM) models which generalize models of gauge mediation. We find superpartner spectra that are markedly different from those of typical gauge and gaugino mediation scenarios. While typical gauge mediation predictions of either a neutralino or stau next-to-lightest supersymmetric particle (NLSP) are easily reproducible with the GGM parameters, chargino and sneutrino NLSPs are generic for many reasonable choices of GGM parameters.
