AI总结:

本文通过连续斯威金格函数方法探讨介子和重子结构,揭示强子质量涌现的三大支柱,并通过π子和质子形式因子的统一解释验证该范式。

摘要:

可见质量的大部分应源于量子色动力学(QCD)中的非微扰动力学。经过多年的发展和完善,连续和格点斯威金格函数方法最近加入了揭示支撑这种涌现的强子质量(EHM)的三大支柱;即非零胶子质量尺度、过程无关的有效电荷,以及具有运行质量的饰化夸克,其在红外动量下取构成类似值。有人认为EHM和束缚是密不可分的;理论现在正在揭示其在强子可观测量中的多种表达,并突出可以进行的测量类型以验证该范式。本文通过π子和质子电磁和引力形式因子的统一解释来阐述这些想法。

英文摘要:

The bulk of visible mass is supposed to emerge from nonperturbative dynamics within quantum chromodynamics (QCD). Following years of development and refinement, continuum and lattice Schwinger function methods have recently joined in revealing the three pillars that support this emergent hadron mass (EHM); namely, a nonzero gluon mass-scale, a process-independent effective charge, and dressed-quarks with running masses that take constituent-like values at infrared momenta. One may argue that EHM and confinement are inextricably linked; and theory is now working to expose their manifold expressions in hadron observables and highlight the types of measurements that can be made in order to validate the paradigm. This contribution sketches these ideas via the unified explanation of pion and proton electromagnetic and gravitational form factors.
