论文摘要
可见物质的特征是单个质量尺度。即质子质量。质子的存在和结构应通过量子染色体动力学（QCD）来描述；然而，没有希格斯玻色子耦合，染色体动力学是规模不变的。因此，如果标准模型确实是自然理论的一部分，则质子质量是QCD的新兴特征。新兴的强子质量（EHM）必须提供理论与观察之间的基本联系。如果要建立这种连接，则需要非扰动工具；在这种情况下，我们勾勒出在连续施温格函数方法应用中应用于强子和粒子物理学中的一系列相关问题的最新进展。 EHM的三个支柱特别强调 - 即运行的gluon质量，与过程无关的有效电荷和运行的夸克质量；它们在稳定QCD中的作用；以及它们在各种可观察到的不同阵列中的可测量表达式。
Visible matter is characterised by a single mass scale; namely, the proton mass. The proton's existence and structure are supposed to be described by quantum chromodynamics (QCD); yet, absent Higgs boson couplings, chromodynamics is scale invariant. Thus, if the Standard Model is truly a part of the theory of Nature, then the proton mass is an emergent feature of QCD; and emergent hadron mass (EHM) must provide the basic link between theory and observation. Nonperturbative tools are necessary if such connections are to be made; and in this context, we sketch recent progress in the application of continuum Schwinger function methods to an array of related problems in hadron and particle physics. Special emphasis is given to the three pillars of EHM -- namely, the running gluon mass, process-independent effective charge, and running quark mass; their role in stabilising QCD; and their measurable expressions in a diverse array of observables.
