论文摘要

本文研究了在混合度量palatini的背景下具有非最小耦合标量场的通货膨胀模型。我们得出爱因斯坦的场方程,即标量场的运动方程。此外,背景和扰动参数是在慢速滚动方程中通过弗里德曼方程获得的。对宇宙扰动的分析使我们能够获得主要的通货膨胀参数,例如标量频谱指数$ n_s $和张量与标量比$ r $。从这个角度来看,作为我们的分析的应用,我们认为具有四重潜力的Higgs领域,它发挥了起源作用,我们表明,HIGGS混合通货膨胀的预测与最近的观察数据\ Cite \ Cite \ cite {akrami:akrami:2018odb}非常吻合。

The inflation model with non-minimal coupling scalar field in the context of the hybrid metric Palatini is studied in this paper. We derive the Einstein's field equations, the equations of motion of the scalar field. Furthermore,the background and the perturbative parameters are obtained by means of Friedmann equation in the slow roll regime. The analysis of cosmological perturbations allowed us to obtain the main inflationary parameters such as the scalar spectral index $n_s$ and the tensor to scalar ratio $r$. In this perspective, as an application of our analysis, we consider the Higgs field with quartic potential which plays the inflaton role, and we show that the predictions of Higgs hybrid inflation are in good agreement with recent observational data \cite{Akrami:2018odb}.
