本文在Higgs门模型的框架下考虑了一个扩展的暴胀模型，假设标量场与引力场的耦合是非最小的。利用Planck的新数据和其他有关天体物理数据，我们得到了非最小耦合和驱动暴胀所需的自耦合之间的关系，并发现这种暴胀模型得到了天体物理数据的支持。此外，我们讨论了粒子物理实验，特别是最近在LHC的Higgs数据对模型参数的约束。
We consider an extended inflation model in the frame of Higgs portal model, assuming a nonminimal coupling of the scalar field to the gravity. Using the new data from Planckand other relevant astrophysical data, we obtain the relation between the nonminimal couplingand the self-couplingneeded to drive the inflation, and find that this inflationary model is favored by the astrophysical data. Furthermore, we discuss the constraints on the model parameters from the experiments of particle physics, especially the recent Higgs data at the LHC.
