论文摘要
在这封信中，我们调查了量规标准在非扰动形式主义中的标准标量波动，用于希格斯的通货膨胀模型，该模型最近在几何标量探测重力理论的框架中引入了。在这种情况下，Higgs Adflaton场具有其起源于背景几何形状的Weyl标量场。我们发现，对于度量标准的线性标量波动的功率谱几乎不变。对于模型的某些参数，我们获得标量频谱索引$ n_s $的值以及与Planck 2018结果非常吻合的标量与张量比$ r $。此外，我们表明在此模型中，可以避免跨普兰克问题。
In this letter we investigate gauge invariant scalar fluctuations of the metric in a non-perturbative formalism for a Higgs inflationary model recently introduced in the framework of a geometrical scalar-tensor theory of gravity. In this scenario the Higgs inflaton field has its origin in the Weyl scalar field of the background geometry. We found a nearly scale invariance of the power spectrum for linear scalar fluctuations of the metric. For certain parameters of the model we obtain values for the scalar spectral index $n_s$ and the scalar to tensor ratio $r$ that fit well with the Planck 2018 results. Besides we show that in this model the trans-planckian problem can be avoided.
