A light neutralino in hybrid models of supersymmetry breaking
Emilian Dudas, Stephane Lavignac, Jeanne Parmentier
TL;DR
This paper explores a hybrid supersymmetry breaking model where gauge mediation with heavy messenger masses from an SU(5) Higgs field results in a light neutralino LSP, integrating gravity mediation for electroweak symmetry breaking.
Contribution
It introduces a novel hybrid gauge-gravity mediation model with a light neutralino LSP arising from heavy messenger masses in an SU(5) framework.
Findings
Neutralino LSP significantly lighter than in standard models
Hybrid model naturally accommodates electroweak symmetry breaking
Gauge mediation spectrum modified by adjoint Higgs field
Abstract
We show that in gauge mediation models where heavy messenger masses are provided by the adjoint Higgs field of an underlying SU(5) theory, a generalized gauge mediation spectrum arises with the characteristic feature of having a neutralino LSP much lighter than in the standard gauge or gravity mediation schemes. This naturally fits in a hybrid scenario where gravity mediation, while subdominant with respect to gauge mediation, provides mu and Bmu parameters of the appropriate size for electroweak symmetry breaking.
