Gaugino masses from misaligned supersymmetry breaking and R-symmetry breaking spurions

TL;DR

This paper explores how gaugino masses can be generated at one loop in gauge mediation models with multiple spurions breaking supersymmetry and R-symmetry separately, under specific R-charge conditions.

Contribution

It introduces a novel mechanism for gaugino mass generation involving misaligned SUSY and R-symmetry breaking spurions, with explicit calculations and example models.

Findings

Gaugino masses can be generated at one loop with specific R-charge arrangements.

Gaugino masses are suppressed by the messenger mass scale.

Two example models demonstrate the feasibility of this mechanism.

Abstract

In gauge mediation models with multiple spurion fields breaking SUSY and the R-symmetry separately, we show that it is possible to generate gaugino masses at one loop if the R-charge arrangement satisfies a certain condition. The resulting gaugino masses are calculated and suppressed by some power of the messenger mass scale. We present two simple examples to demonstrate this possibility, and discuss possible phenomenology implications.
