国内外介子束流实验的发展现状和未来计划

Development Status and Future Plan of Meson Beam Experiments at Home and Abroad

  • 摘要: 介子束流与原子核碰撞实验在中高能核物理和粒子物理研究领域发挥了重要推动作用,特别是在强子谱研究方面取得了一系列重要实验测量结果。本工作对目前国际上几个比较典型的介子束流实验进行了梳理与总结,这包括了位于日本的J-PARC实验、欧洲核子中心的COMPASS实验、AMBER实验以及计划中的HIKE实验、美国JLab的GlueX实验和EIC项目。进一步,基于国内的HIAF装置对可能产生的次级介子束流的参数指标进行了分析估算,并讨论了可以开展地相关物理测量。通过对这些实验项目的调研分析,旨在为进一步规划和建造我国的介子束流实验装置并开展强子物理方面的研究有所启发和借鉴。

     

    Abstract: Meson beam and nucleus collision experiments have played an important role in the field of nuclear physics and particle physics at medium and high energies, especially in the study of hadron spectroscopy, where a series of important experimental measurements have been achieved. In this paper, several typical meson beam experiments in the world are summarized, including J-PARC experiment in Japan, COMPASS experiment, AMBER experiment and HIKE experiment planned at CERN, GlueX experiment and EIC project at JLab in the United States. Furthermore, parameters of secondary meson beam are estimated based on HIAF facility in China, and physical measurements are discussed. Through the investigation of these experimental projects, the purpose is to provide some inspiration and reference for the further planning and construction of meson beam experimental equipment in China and the related research on hadron physics.
