标题： Higgs-Modular Inflation

摘要： 我们研究希格斯场在标准模型中作为基本标量的作用，在模膨胀模型框架下，其中模场作为暴胀子，其相互作用由底层的模对称性支配。 通常，希格斯场可以参与模膨胀的动力学，导致一个两场膨胀系统——称为\emph{希格斯模形式膨胀}——表现出非平凡的动力学和有趣的现象学含义。 我们对希格斯-模膨胀进行了分析和数值分析，强调其吸引子行为和由此产生的观测约束。 特别是，我们发现希格斯-模膨胀在参数空间的某些区域受到阿塔卡马宇宙学望远镜（ACT）最新数据发布的青睐。 这与纯希格斯膨胀和具有Starobinsky型势的纯模膨胀形成对比，后者倾向于预测相对较低的谱指数。 此外，我们讨论了该膨胀模型的截断尺度以及由模场和希格斯场衰变引起的再加热过程。 显示英文摘要

摘要： We investigate the role of the Higgs field as a fundamental scalar in the Standard Model within the framework of modular inflation models, where a modulus field acts as the inflaton and its interactions are governed by an underlying modular symmetry. In general, the Higgs field can participate in the dynamics of modular inflation, leading to a two-field inflationary system-termed \emph{Higgs-Modular inflation}-which exhibits non-trivial dynamics and interesting phenomenological implications. We analyze Higgs-Modular inflation both analytically and numerically, highlighting its attractor behavior and the resulting observational constraints. In particular, we find that Higgs-Modular inflation is favored by the latest data release from the Atacama Cosmology Telescope (ACT) in certain regions of parameter space. This is in contrast to both pure Higgs inflation and pure modular inflation with a Starobinsky-type potential, which tend to predict a relatively low spectral index. Additionally, we discuss the cutoff scale of this inflationary model and the reheating processes induced by the decays of the modulus and the Higgs field.
