论文摘要
我们表明，可以在具有三个右中微子，三个复杂标量和一个测量的Lepton/B-L U（1）对称性的标准模型的最小扩展中实现温暖的通货膨胀。这个简单的模型可以解决标准模型的所有缺点，这些缺点与一般相对性中的微调无关，并具有独特的实验签名，可以在不久的将来进行探测。充气场来自U（1）对称性的集体破裂，并与两个右手中微子相互作用，在通货膨胀期间维持了高温辐射浴。该模型的离散交换对称性可保护标量电势免受大型热校正的影响，并在后期导致稳定的充气残留物，这可以解释暗物质。模型的一致性和与宇宙微波背景观测的一致性自然产生低于0.1 eV的光中微子质量，而热静脉生成自然发生在从通货膨胀到辐射时代的平稳退出后。
We show that warm inflation can be realized within a minimal extension of the Standard Model with three right-handed neutrinos, three complex scalars and a gauged lepton/B-L U(1) symmetry. This simple model can address all the shortcomings of the Standard Model that are not related to fine-tuning, within general relativity, with distinctive experimental signatures that can be probed in the near future. The inflaton field emerges from the collective breaking of the U(1) symmetry, and interacts with two of the right-handed neutrinos, sustaining a high-temperature radiation bath during inflation. The discrete interchange symmetry of the model protects the scalar potential against large thermal corrections and leads to a stable inflaton remnant at late times which can account for dark matter. Consistency of the model and agreement with Cosmic Microwave Background observations naturally yield light neutrino masses below 0.1 eV, while thermal leptogenesis occurs naturally after a smooth exit from inflation into the radiation era.
