摘要：
我们调查的预测单场模型的通货膨胀是强大的额外的标量自由度的引入下，以及这些额外的字段是否改变的潜力，数据显示最强的偏好。我们研究的情况下，额外的光标量场有助于总曲率扰动和再热运动学性质。确定了10个再加热方案，并推导出所有必要的公式，允许系统计算这类模型的预测。它们在公共图书馆ASPIC中实现，其中包含超过75个单场电位。这为即将对该问题进行全面的贝叶斯分析铺平了道路。一些有代表性的例子显示和讨论。
英文摘要：
We investigate whether the predictions of single-field models of inflation are robust under the introduction of additional scalar degrees of freedom, and whether these extra fields change the potentials for which the data show the strongest preference. We study the situation where an extra light scalar field contributes both to the total curvature perturbations and to the reheating kinematic properties. Ten reheating scenarios are identified, and all necessary formulas allowing a systematic computation of the predictions for this class of models are derived. They are implemented in the public library ASPIC, which contains more than 75 single-field potentials. This paves the way for a forthcoming full Bayesian analysis of the problem. A few representative examples are displayed and discussed.
