“…The misalignment between SUSY breaking and R-symmetry breaking spurions may arise not only in tree-level R-symmetry breaking models [28,29,34], but also in models with separate SUSY breaking and R-symmetry breaking sectors. Recently found counterexamples to the Nelson-Seiberg theorem show the possibility of R-symmetry breaking spurions that do not break SUSY [12,13,15,18]. Thus, there may be more freedom to manipulate the mass spectrum of gauginos, as well as other SUSY breaking soft terms, by independently adjusting the SUSY breaking and R-symmetry breaking effects in different sectors.…”

“…The R-charge assignment of fields determines the generic form of the superpotential, which has R-charge 2. SUSY or SUSY breaking vacua can be obtained by a proper R-charge assignment satisfying certain conditions [10][11][12][13][14][15][16][17][18][19][20]. SUSYbreaking effects are transferred to the visible sector through the coupling of messenger fields.…”

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 in one loop if the R-charge arrangement satisfies a certain condition. The resulting gaugino masses are calculated and suppressed by a power of the messenger’s mass scale. We present two simple examples to demonstrate this possibility and discuss possible phenomenology implications.

The Nelson-Seiberg theorem dictates conditions for the spontaneous breaking of the supersymmetry in Wess–Zumino models with generic, possibly nonrenormalizable, superpotential; the existence of the R-symmetry is necessary while the spontaneous breaking of the R-symmetry is sufficient. If we restrict ourselves to generic but renormalizable theories, however, there exist Wess–Zumino models whose vacua break the R-symmetry spontaneously while preserving the supersymmetry. The classification and conditions of such renormalizable exceptions are under active study. We give some new examples of spontaneous breaking of the R-symmetry with preserved supersymmetry that are not covered in the literature.
