我们提出了在物质耦合N= 1四维超引力中的Starobinsky型暴胀模型，该模型的场分量中含有暴胀子（标量子）和goldstino，其作用量包括Dirac-Born-Infeld型动力学项和广义（新）Fayet-Iliopoulos型项，而不考虑R对称性. N= 1的手征物质（“隐藏扇区”）由膨胀后自发超对称破缺所需的修改的Polonyi模型描述。我们计算了该模型的玻色子作用量和标量势，证明了它可以容纳正的（观测到的）宇宙学常数（作为暗能量）和Starobinsky暴胀后高尺度下自发的超对称破缺.
We propose the Starobinsky-type inflationary model in the matter-coupled N= 1 four-dimensional supergravity with the massive vector multiplet that has inflaton (scalaron) and goldstino amongst its field components, whose action includes the Dirac–Born–Infeld-type kinetic term and the generalized (new) Fayet–Iliopoulos-type term, without gauging the R-symmetry. The N= 1 chiral matter ('hidden sector') is described by the modified Polonyi model needed for spontaneous supersymmetry breaking after inflation. We compute the bosonic action and the scalar potential of the model, and show that it can accommodate the positive (observed) cosmological constant (as the dark energy) and the spontaneous supersymmetry breaking at high scale after the Starobinsky inflation.
