标题： Chromo-natural warm inflation

摘要： 染色自然暴胀是一个模型，其中非阿贝尔规范场通过轴子与规范场通过陈-西蒙斯项的耦合而得以维持。 虽然最小温暖暴胀是一个模型，其中轴子通过陈-西蒙斯项产生非阿贝尔规范粒子的热浴。 由于这两种轴子暴胀模型基于相同的作用量，一个自然的问题是它们是否相容。 我们研究带有陈-西蒙斯项的轴子暴胀，并发现染色自然暴胀可以在暴胀期间容纳温度远大于哈勃参数的辐射，这是温暖暴胀的一个特征特性。 因此，我们得出结论，染色自然温暖暴胀存在，这必须具有现象学上有趣的后果。 显示英文摘要

摘要： Chromo-natural inflation is a model where non-abelian gauge fields are sustained by the coupling of the axion with the gauge field through the Chern-Simons term. While minimal warm inflation is a model where the axion produces a thermal bath of non-abelian gauge particles through the Chern-Simons term. Since both axion inflation models are based on the same action, a natural question is if those are compatible or not. We study axion inflation with the Chern-Simons term and find that chromo-natural inflation can accommodate radiation with a temperature much larger than the Hubble parameter during inflation, which is a characteristic feature of warm inflation. Thus, we conclude that chromo-natural warm inflation exists, which must have phenomenologically interesting consequences.
