论文摘要
我们建立了广义Proca有效场理论的辐射稳定性。虽然标准的电源参数可以得出结论,但我们通过明确计算发散的单循环图最多四点来发现领先顺序校正的不平凡取消。这些结果通过有效的基于动作的广义schwinger-dewitt方法进行了交叉检查。此外,取消被理解为通过解耦极限分析的特定结构,同时允许将结果扩展到更高的阶段。
We establish radiative stability of generalized Proca effective field theories. While standard powercounting arguments would conclude otherwise, we find non-trivial cancellations of leading order corrections by explicit computation of divergent one-loop diagrams up to four-point. These results are crosschecked against an effective action based generalized Schwinger-DeWitt method. Further, the cancellations are understood as coming from the specific structure of the theory through a decoupling limit analysis which at the same time allows for an extension of the results to higher orders.
