论文摘要
据推测，在压实时空中发现的半古典物体的bions负责取消所谓的肾上腺含量歧义。与猜想相反，我们认为由于Bion引起的歧义与Feynman图的扩散相对应。我们指出，由于在$ s^1 $压实和扭曲的边界条件下的红外结构的修改，几乎所有Feynman图的幅度都得到了增强。我们的发现阐明了半古典物体在复兴结构中的作用，这是近年来的一个有争议的问题。
It was conjectured that bions, semi-classical objects found in a compactified spacetime, are responsible for the cancellation of the so-called renormalon ambiguities. Contrary to the conjecture, we argue that the ambiguity due to the bion corresponds to the proliferation of Feynman diagrams. We point out that the amplitudes of almost all Feynman diagrams are enhanced due to modifications of the infrared structure of perturbation theory upon an $S^1$ compactification and twisted boundary conditions. Our findings clarify the role of the semi-classical object in resurgence structure, which has been a controversial issue in recent years.
