Abstract

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.

伪谱介子与新兴质量

尽管希格斯玻色子在宇宙的持续演化中扮演着重要角色，但只有一小部分可见物质的质量可以单独归因于希格斯玻色子。占压倒性优势的部分可能/应该来自作用于核物质核心的强相互作用，即量子色动力学所描述的相互作用。这篇论文描述了研究和解释伪星介子的属性如何为理解标准模型中质量的起源打开一扇富有洞察力的窗口，以及这些洞察力如何为我们了解强子结构提供信息。调查范围包括分布振幅和函数、电磁和引力形式因子、光前波函数以及广义的部分子分布。重点介绍了利用连续施温格函数方法取得的进展及其与实验工作的相关性。

期刊介绍： The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures. Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal. The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
