论文摘要
旧的$ r+r^2 $ supergravity具有$ u（1）$ r-对称性，可旋转手性曲率超级场。我们评估了这种R-对称性，并研究了在通货膨胀和超对称性破坏的背景下涉及量规多重组的新相互作用。我们构建模型，在Starobinsky通货膨胀期间和之后，超对称性和R-对称性自发断裂，并且绿色 - schwarz机制也可以消除一环量规异常，该机制也可以生成标准的模型gaugino块。辅助字段之间的层次结构，$ \ langle f \ rangle \ gtrsim \ langle d \ rangle $，导致分裂的质量频谱，其中手性多重质量围绕通货膨胀量表（$ 10^{13} $ gev），而衡量标准群可以仲裁。
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 cancelled by the Green--Schwarz mechanism which can also generate Standard Model gaugino masses. The hierarchy between the auxiliary fields, $\langle F\rangle\gtrsim\langle D\rangle$, 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.
