Direct Mediation and Metastable Supersymmetry Breaking for SO(10)

TL;DR

This paper investigates metastable supersymmetry breaking in an SO(10) SQCD model, introducing deformations and embedding into the Standard Model, with detailed analysis of messenger mechanisms and mass spectra.

Contribution

It presents a novel embedding of SO(10) into metastable SUSY breaking models with various deformations and analyzes messenger-mediated SUSY breaking to the MSSM.

Findings

Gaugino and sfermion masses are computed for different deformations.

Embedding SO(10) into weakly gauged sectors is feasible.

An additional fundamental messenger is identified when reducing the magnetic quark matrix rank.

Abstract

We examine a metastable $\mathcal{N}=1$ Macroscopic SO(N) SQCD model of Intriligator, Seiberg and Shih (ISS). We introduce various baryon and meson deformations, including multitrace operators and explore embedding an SO(10) parent of the standard model into two weakly gauged flavour sectors. Direct fundamental messengers and the symmetric pseudo-modulus messenger mediate SUSY breaking to the MSSM. Gaugino and sfermion masses are computed and compared for each deformation type. We also explore reducing the rank of the magnetic quark matrix of the ISS model and find an additional fundamental messenger.
