不稳定粒子和共振的Dyson级数修正
Modifying the Dyson Series for Unstable Particles and Resonances
摘要：
在这项工作中，我们介绍了一个修改的戴森系列的基础上微扰么正性作为一个出发点。所提出的方法系统地避免了与不稳定粒子作为中间态的存在相关的奇异性和双重计数，同时，它不依赖于重整化方案的特定选择。
英文摘要：
In this work, we introduce a modification of the Dyson series based on the perturbative unitarity as a starting point. The presented approach systematically avoids singularities and double-counting related to the presence of unstable particles as intermediate states and, at the same time, it does not rely on a specific choice of the renormalization scheme.
