我们研究了最近提出的一个纯自然暴胀模型中暴胀子的形成，其中暴胀子是一个耦合到强耦合纯杨-米尔斯理论的轴子。暴胀子势的平台，这是最近的观测所青睐的，驱动暴胀子的碎裂，并可以产生空间局域的光子。我们发现，在模型的有效衰变常数为。我们还评论的观测影响的的电子。
We examine the oscillon formation in a recently proposed inflation model of thepure natural inflation, where the inflaton is an axion that couples to a strongly coupled pure Yang-Mills theory. The plateau of the inflaton potential, which is favored by recent observations, drives the fragmentation of the inflaton and can produce spatially localized oscillons. We find that the oscillons are formed for, withthe effective decay constant of the model. We also comment on observational implications of the oscillons.
