The aim of the hadron physics research programs conducted at J-PARC is to explore the structure of hadronic matter using the world's highest-intensity meson beams. Since the first beam was extracted at the hadron experimental facility (HEF) in February 2009, a wide variety of physics experiments have been proposed and performed to address open questions regarding quantum chromodynamics (QCD) at low energy. The high-intensity $K^-$ and high-momentum beams available at J-PARC open a new era in hadron and nuclear physics, in which strange and charm quarks play an important role. We review the programs focused on addressing the hadron structure as strongly interacting composite particles, the origin of hadron mass, and interactions between hadrons under broken flavor SU(3) symmetry.

J-PARC 的强子物理学

在 J-PARC 进行的强子物理研究计划的目的是使用世界上强度最高的介子束探索强子物质的结构。自从 2009 年 2 月在强子实验设施 (HEF) 提取第一束光束以来，已经提出并执行了各种各样的物理实验，以解决有关低能量量子色动力学 (QCD) 的开放性问题。J-PARC 提供的高强度 $K^-$ 和高动量光束开启了强子和核物理学的新时代，其中奇夸克和魅力夸克起着重要作用。我们回顾了专注于将强子结构作为强相互作用复合粒子、强子质量的起源以及破坏风味 SU(3) 对称性下强子之间相互作用的程序。
