标题： Unified Origin of Inflation, Baryon Asymmetry, and Neutrino Mass

摘要： 在这项工作中，我们提出了一种统一的理论框架，同时解决了粒子物理和宇宙学中一些最引人入胜的谜题，即中微子质量的起源、重子不对称性和宇宙暴胀的起源。 在我们的模型中，暴胀由标准模型希格斯场、负责中微子质量生成的II型 seesaw 希格斯以及统一对称性破缺希格斯场的组合驱动。 在暴胀期间，后者的非零值确保了单极子问题的不存在。 重子不对称性通过Affleck-Dine机制生成，该机制由复标量场相位中的非零角运动促成，该复标量场是暴胀子的一部分。 我们发现，通过标量势中的可重整化项生成重子不对称性的成功参数区域需要一个相当重的II型seesaw三重态，其质量远超TeV尺度。 暴胀观测值，特别是光谱指数与实验观测结果高度一致，而张量与标量比预计将由未来的LiteBIRD和CMB-S4任务进行探测。 显示英文摘要

摘要： In this work, we present a unified theoretical framework that simultaneously addresses some of the most intriguing puzzles in particle physics and cosmology, namely the origins of neutrino mass, baryon asymmetry, and cosmic inflation. In our model, inflation is driven by a combination of the Standard Model Higgs, the type II seesaw Higgs responsible for neutrino mass generation, and the unified symmetry-breaking Higgs field. During inflation, non-zero values of the latter field ensure the absence of the monopole problem. The baryon asymmetry is generated through the Affleck-Dine mechanism, facilitated by the non-zero angular motion in the phase of a complex scalar field, which is part of the inflaton. We find that the successful parameter region for generating baryon asymmetry through a renormalizable term in the scalar potential requires a rather heavy type II seesaw triplet, with a mass well beyond the TeV scale. Inflationary observables, in particular, the spectral index is in excellent agree with experimental observation, whereas tensor-to scalar ratio is expected to be probed by the future LiteBIRD and CMB-S4 missions.
