We construct a unified model of inflation and PeV dark matter with an appropriate choice of no-scale Kähler potential, superpotential, and gauge kinetic function in terms of MSSM fields and hidden sector Polonyi field. The model is consistent with the CMB observations and can explain the PeV neutrino flux observed at IceCube HESE. A Starobinsky-like Higgs-sneutrino plateau inflation is obtained from the -term SUGRA potential while -term being subdominant during inflation. To get PeV dark matter, SUSY breaking at PeV scale is achieved through Polonyi field. This sets the scale for soft SUSY breaking parameters at the GUT scale in terms of the parameters of the model. The low-energy particle spectrum is obtained by running the RGEs. We show that the ~125 GeV Higgs and the gauge coupling unification can be obtained in this model. The 6 PeV bino-type dark matter is a subdominant fraction (~11%) of the relic density, and its decay gives the PeV scale neutrino flux observed at IceCube by appropriately choosing the couplings of the -parity violating operators. Also, we find that there is degeneracy in scalar field parameters and coupling value in producing the correct amplitude of CMB power spectrum. However, the value of parameter , which is tightly fixed from the requirement of PeV scale SUSY breaking, removes the degeneracy in the values of the scalar field parameters to provide a unique solution for inflation. In this way, it brings the explanation for dark matter, PeV neutrinos, and inflation within the same framework.

PeV暗物质衰减的膨胀超重力模型并解释IceCube HESE数据

我们构建了一个通货膨胀和PeV暗物质的统一模型，可以选择无尺度Kähler势，超势和规范动力学函数（根据MSSM场和隐含扇区Polonyi场）。该模型与CMB观测结果一致，并且可以解释IceCube HESE观测到的PeV中微子通量。甲斯塔罗宾斯基状希格斯-sneutrino高原通货膨胀从获得的-术语SUGRA潜力，同时-术语膨胀期间是亚优势。为了获得PeV暗物质，通过Polonyi场实现了以PeV规模破碎SUSY。设置软SUSY断裂参数的标度根据模型的参数在GUT尺度上。通过运行RGE获得低能粒子光谱。我们表明，在此模型中可以获得〜125 GeV希格斯和轨距耦合的统一。6 PEV BINO型暗物质是遗迹密度的亚优势部分（〜11％），及其衰变给出通过适当地选择的联轴器在冰块观察到通量的PEV规模中微子-奇偶性违反操作人员。此外，我们发现标量场参数存在退化和耦合值以产生正确的CMB功率谱幅度。但是，参数的值，其被紧紧地从PEV规模超对称断裂的要求固定的，去除在标量场参数的值的简并性，以提供通货膨胀独特的解决方案。这样，它在同一框架内为暗物质，PeV中微子和膨胀提供了解释。
