赝标量介子与涌现质量

Pseudoscalar Mesons and Emergent Mass

K. Raya, A. Bashir, D. Binosi, C. D. Roberts, J. Rodríguez-Quintero

AI总结:

该研究围绕标准模型中可见物质质量的起源问题,指出强相互作用是质量的主要来源,通过研究赝标量介子的各类属性与相关理论方法,为理解质量起源和强子结构提供了新视角。

摘要:

尽管希格斯玻色子在宇宙的持续演化中发挥着作用,但可见物质的质量中仅有一小部分可单独归因于希格斯玻色子。占绝对主导地位的质量份额可能/应当源自核物质核心处的强相互作用,即量子色动力学所描述的相互作用。本文阐述了研究并解释赝标量介子的属性如何为理解标准模型中的质量起源打开一扇富有洞见的窗口,以及这些洞见如何增进我们对强子结构的认知。本综述涵盖了分布振幅与分布函数、电磁与引力形状因子、光前波函数以及广义部分子分布。本文重点介绍了利用连续体施温格函数方法取得的进展,以及这些进展与实验工作的相关性。

英文摘要:

Despite its role in the continuing evolution of the Universe, only a small fraction of the mass of visible material can be attributed to the Higgs boson alone. The overwhelmingly dominant share may/should arise from the strong interactions that act in the heart of nuclear matter; namely, those described by quantum chromodynamics. This contribution describes how studying and explaining the attributes of pseudoscalar mesons can open an insightful window onto understanding the origin of mass in the Standard Model and how these insights inform our knowledge of hadron structure. The survey ranges over distribution amplitudes and functions, electromagnetic and gravitational form factors, light-front wave functions, and generalized parton distributions. Advances made using continuum Schwinger function methods and their relevance for experimental efforts are highlighted.
