我们回顾了一种自上而下的不动点外推范式，作为统一的有效场论框架，用于强子谱学、致密重子物质和致密星物理。通过直接在重整化群（RG）不动点处构建有效拉格朗日量并引入最小对称性破缺，我们将理论外推回物理环境。在真空中，该框架通过轻矢量介子圈自然重现了重-轻介子奇偶倍增谱。在致密物质中，手征不变核子质量m0与行走矢量耦合之间的相互作用调和了引力波约束与$2M_\odot$大质量中子星。推广到夸克-强子混合方法进一步阐明了循序退禁闭、核心稳定性及重子数涨落，展示了底层RG不动点如何从真空到中子星内部主导强子动力学。
英文摘要
We review a top-down fixed-point-extrapolation paradigm as a unified effective field theory framework for hadronic spectroscopy, dense baryonic matter, and compact star physics. By formulating our effective Lagrangian directly at renormalization group (RG) fixed points and introducing minimal symmetry breaking, we extrapolate the theory back to physical environments. In the vacuum, this framework naturally reproduces the heavy-light meson parity-doubling spectrum via light vector meson loops. In dense matter, the interplay between the chiral-invariant nucleon mass m0 and walking vector couplings reconciles gravitational-wave constraints with $2M_\odot$ massive neutron stars. Generalization to a quark-hadron hybrid approach further illuminates sequential deconfinement, core stability, and baryon number fluctuations, demonstrating how underlying RG fixed points dictate hadronic dynamics from vacuum to neutron star interiors.
