广义Proca理论的量子稳定性

Quantum Stability of Generalized Proca Theories

Lavinia Heisenberg, Jann Zosso

摘要:

建立了广义Proca有效场论的辐射稳定性。虽然标准的powercounting参数会得出结论,否则,我们发现非平凡的取消领导秩序的纠正明确计算发散单循环图四点。这些结果与基于有效作用的广义Schwinger-DeWitt方法进行了交叉检验。此外,取消被理解为来自特定的理论结构,通过解耦极限分析,在同一时间允许的结果扩展到更高的订单。

英文摘要:

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.
