论文摘要
We propose a novel model of the modified (Starobinsky-like) old-minimal-type supergravity coupled to a chiral matter superfield, that can {\it simultaneously} describe multi-field inflation, primordial black hole (PBH) formation, dark matter (DM), and spontaneous supersymmetry (SUSY) breaking after inflation in a Minkowski vacuum.我们的双重慢速通胀模型中的PBH质量在两个慢速倾斜相之间的短期“超慢滚”阶段接近$ 10^{18} $ g。我们发现，在允许的质量窗口中的显着PBH部分可以通过自发的Susy在真空中破裂，而gravitino质量接近Scalaron（Inflaton）质量为$ 10^{13} $ GEV。我们的超级重力模型倾向于DM作为PBH和重力重力的混合物的{\ IT复合}性质作为最轻的SUSY颗粒。整个PBH-DM所需的复合DM显着放松了微调。 PBH-DM馏分是得出的，并计算出增强标量扰动引起的二阶重力波背景。这些引力波可以通过未来的空间重力干涉仪来访问。
We propose a novel model of the modified (Starobinsky-like) old-minimal-type supergravity coupled to a chiral matter superfield, that can {\it simultaneously} describe multi-field inflation, primordial black hole (PBH) formation, dark matter (DM), and spontaneous supersymmetry (SUSY) breaking after inflation in a Minkowski vacuum. The PBH masses in our supergravity model of double slow-roll inflation, with a short phase of "ultra-slow-roll" between two slow-roll phases, are close to $10^{18}$ g. We find that a significant PBH fraction in the allowed mass window can be supplemented by spontaneous SUSY breaking in the vacuum with the gravitino mass close to the scalaron (inflaton) mass M of the order $10^{13}$ GeV. Our supergravity model favors the {\it composite} nature of DM as a mixture of PBH and heavy gravitinos as the lightest SUSY particles. The composite DM significantly relaxes fine-tuning needed for the whole PBH-DM. The PBH-DM fraction is derived, and the second-order gravitational wave background induced by the enhanced scalar perturbations is calculated. Those gravitational waves may be accessible by the future space-based gravitational interferometers.
