Gauging the R symmetry of old minimal R plus R2 supergravity

Old minimal R + R(2 )supergravity has a U(1) R symmetry which rotates the chiral curvature superfield. We gauge this R symmetry and study new interactions involving the gauge multiplet in the context of inflation and supersymmetry breaking. We construct models where supersymmetry and the R symmetry are spontaneously broken during and after Starobinsky inflation, and one-loop gauge anomalies are canceled by the Green-Schwarz mechanism which can also generate Standard Model gaugino masses. The hierarchy between the auxiliary fields, < F > greater than or similar to < D >, leads to split mass spectrum where the chiral multiplet masses are around the inflationary scale (10(13) GeV), while the gauge multiplet masses can be arbitrarily small.
