TL;DR
This paper investigates how D-term effects influence runaway directions in F-term scalar potentials, presenting a minimal model that breaks supersymmetry without pseudomoduli and applies it to gauge mediation for R-symmetry breaking.
Contribution
It introduces a minimal renormalizable model that breaks supersymmetry without pseudomoduli and demonstrates R-symmetry breaking in gauge mediation.
Findings
Supersymmetry is broken without pseudomoduli in the model.
R symmetry is spontaneously broken in the hidden sector.
Gaugino masses are generated at one-loop order.
Abstract
We study the D-term effect on runaway directions of the F-term scalar potential. A minimal renormalizable model is presented where supersymmetry is broken without any pseudomoduli. The model is applied to the hidden sector of gauge mediation for spontaneously breaking R symmetry and generating nonvanishing gaugino masses at the one-loop order.
