论文摘要
我们建议在弯曲空间中稍微概括DeWitt-Schwinger绝热的重生减法,以包括任意重新归一化的质量尺度$μ$。重力耦合的新预测运行与重大田地的脱钩完全一致。对于通过尺寸正则化的最小(Dewitt-Schwinger)减法的更标准治疗方法,这是一个有所改善的。我们还展示了真空变态模型是如何从运行耦合中出现的。
We propose to slightly generalize the DeWitt-Schwinger adiabatic renormalization subtractions in curved space to include an arbitrary renormalization mass scale $μ$. The new predicted running for the gravitational couplings are fully consistent with decoupling of heavy massive fields. This is a somewhat improvement with respect to the more standard treatment of minimal (DeWitt-Schwinger) subtractions via dimensional regularization. We also show how the vacuum metamorphosis model emerges from the running couplings.
