In this work, we study inflation with the non-minimally coupled quadratic, Standard Model (SM) Higgs and hilltop potentials through $\xi \phi^2R$ term in the Palatini gravity. We first analyze observational parameters of Palatini quadratic potential as functions of $\xi$ for high-$N$ scenario and low-$N$ scenario. In addition to this, taking into account inflaton $\phi$ has a non-zero vacuum expectation value $v$ afterwards inflation, we display observational parameters of well-known symmetry-breaking potentials type of Higgs potential and its generalizations which are hilltop potentials in the Palatini formalism for high-$N$ scenario and low-$N$ scenario. We calculate inflationary parameters of Palatini Higgs potential as functions of $v$ for different $\xi$ values where inflaton values both $\phi>v$ and $\phi

帕拉蒂尼引力中的二次、希格斯和山顶势

在这项工作中,我们通过帕拉蒂尼引力中的 $\xi \phi^2R$ 项研究了非最小耦合二次、标准模型 (SM) 希格斯和山顶势的膨胀。我们首先将 Palatini 二次势的观测参数分析为高 $N$ 情景和低 $N$ 情景的 $\xi$ 函数。除此之外,考虑到暴胀子 $\phi$ 在暴胀之后具有非零真空期望值 $v$,我们展示了著名的对称破缺势类型希格斯势及其推广的观测参数,即山顶势在 Palatini 形式主义中,高 $N$ 场景和低 $N$ 场景。我们计算帕拉蒂尼希格斯势的膨胀参数作为不同 $\xi$ 值的 $v$ 函数,其中 inflaton 值 $\phi>v$ 和 $\phi
