TL;DR
This paper introduces an R-symmetric gauge mediation framework that results in Dirac gauginos, zero A-terms, and four Higgs doublets, offering an alternative supersymmetry-breaking mechanism with distinctive phenomenology.
Contribution
It proposes a novel R-symmetric gauge mediation model with unique features like Dirac gauginos and multiple Higgs doublets, expanding the landscape of supersymmetry-breaking scenarios.
Findings
Gauginos are Dirac particles in this framework.
The model naturally suppresses A-terms.
It explores the realization of specific sfermion spectra and mixing.
Abstract
We present a version of Gauge Mediated Supersymmetry Breaking which preserves an R-symmetry - the gauginos are Dirac particles, the A-terms are zero, and there are four Higgs doublets. This offers an alternative way for gauginos to acquire mass in the supersymmetry-breaking models of Intriligator, Seiberg, and Shih. We investigate the possibility of using R-symmetric gauge mediation to realize the spectrum and large sfermion mixing of the model of Kribs, Poppitz, and Weiner.
