TL;DR

This paper extends the general gauge mediation framework to include Dirac gaugino masses, demonstrating how to generate these masses and discussing implications for supersymmetry breaking models.

Contribution

It introduces a formalism for incorporating Dirac gaugino masses into gauge mediation, expanding the theoretical tools for supersymmetry model building.

Findings

Reproduces known results for gaugino and sfermion masses with R-symmetry

Shows how to generate same sign masses for adjoint scalars

Comments on U(1) mixing in the formalism

Abstract

We extend the formulation by Meade, Seiberg and Shih of general gauge mediation of supersymmetry breaking to include Dirac masses for the gauginos. These appear through mixing of the visible sector gauginos with additional states in adjoint representations. We illustrate the method by reproducing the existing results in the literature for the gaugino and sfermion masses when preserving R-symmetry. We then explain how the generation of same sign masses for the two propagating degrees of freedom in the adjoint scalars can be achieved. We end by commenting on the use of the formalism for describing U(1) mixing.
