We present the impact of non-minimal coupling ξϕ² R on the inflationary parameters by taking into account the models of single-field inflation with the inflaton that has a non-zero vacuum expectation value (v) after the period of inflation in Palatini gravity. We discuss the well-known symmetry-breaking type potentials, namely the double-well potential and Coleman-Weinberg potential. We show that the inflationary predictions, n _s and r, of these potentials for both ϕ > v and ϕ < v inflation are compatible with the recent measurements within the regions of the v-ξ plane. Finally, we take into account the inflationary predictions of Coleman-Weinberg potential for selected ξ values as a function of v in the Palatini formalism.

我们通过考虑在帕拉蒂尼重力暴胀期后具有非零真空期望值 ( v ) 的暴胀子的单场暴胀模型，展示了非最小耦合 ξφ ² R对暴胀参数的影响. 我们讨论了著名的对称破坏型势，即双阱势和 Coleman-Weinberg 势。我们表明，对于 ϕ > v和 ϕ < v暴胀的这些势能的暴胀预测n _s和r与v区域内最近的测量结果是一致的。 -ξ 平面。最后，我们考虑了 Coleman-Weinberg 对选定 ξ 值的膨胀预测，作为帕拉蒂尼形式主义中v的函数。
