Borel平面外的重正马龙

Renormalons beyond the Borel plane

Erich Cavalcanti

摘要:

重正马龙奇点是场论模型中渐近微扰级数发散行为的一个已知来源。这些奇点存在于波莱尔平面中,并负责物理平面中的二义性。我们提出场论可以有超出通常的第一Borel平面的重整化子。我们展示了一个标量场理论的例子,考虑到猫的眼睛图链,该模型开发了Gevrey-3渐近级数。

英文摘要:

The renormalon singularities are a known source of the divergent behavior of asymptotic perturbative series from field theoretical models. These singularities live in the Borel plane and are responsible for ambiguities in the physical plane. We propose that field theories can have renormalons beyond the usual first Borel plane. We show an example with a scalar field theory where, considering a chain of cat's eyes diagrams, the model develops a Gevrey-3 asymptotic series.
