论文摘要
有效的现场理论提供了关于重新归一化组固定点的预测能力的新观点。不同固定点之间的临界轨迹限制了UV-Complete，IR-Complete和保形理论的区域。相关的边界表面不能通过任何有效的场理论的重新归一化组流动。我们描述了边界表面充当通用有效场理论的红外吸引子的情况。量规野川理论既是扰动又具有直接现象学兴趣的例子。我们确定其他物质字段，使得标准模型的所有观察到的耦合值（除了阿贝尔超负荷）外，也位于保形区域内。我们定义了有效渐近安全性预测性的定量度量，并证明了与标准模型Yukawa耦合相关的相关的现象学约束。
Effective field theory provides a new perspective on the predictive power of Renormalization Group fixed points. Critical trajectories between different fixed points confine the regions of UV-complete, IR-complete, as well as conformal theories. The associated boundary surfaces cannot be crossed by the Renormalization Group flow of any effective field theory. We delineate cases in which the boundary surface acts as an infrared attractor for generic effective field theories. Gauge-Yukawa theories serve as an example that is both perturbative and of direct phenomenological interest. We identify additional matter fields such that all the observed coupling values of the Standard Model, apart from the Abelian hypercharge, lie within the conformal region. We define a quantitative measure of the predictivity of effective asymptotic safety and demonstrate phenomenological constraints for the associated beyond Standard-Model Yukawa couplings.
