论文摘要
J-PARC是一家强子加速器设施，可提供Kaons，Pions，Neutminos，Muons和其他的二级光束以及主要的质子束，用于研究广泛的科学项目。可以通过使用未分离的Hadron的高摩肌束（本质上是乳腺质子，也是原代质子）来研究高能量强生理物理学。在本报告中，对颜色透明度和广义Parton分布（GPD）进行了可能的解释。这些项目是在JLAB，Compass/Amber和未来电子离子界面的Lepton散落实验的补充。由于高达30 GEV的强子梁的能量，J-PARC是研究从强子自由度到夸克 - 格鲁隆的独特设施。它适合查找颜色透明度的机制。此类颜色透明度研究对于阐明从实际测量中提取GPD的强子产生过程的分解也很有价值。这些研究将导致理解核培养基中基本的高能强体相互作用，并澄清强子旋转，质量和内部压力机制的起源。
The J-PARC is a hadron-accelerator facility to provide secondary beams of kaons, pions, neutrinos, muons, and the others together with the primary proton beam for investigating a wide range of science projects. High-energy hadron physics can be studied by using high-momentum beams of unseparated hadrons, which are essentially pions, and also primary protons. In this report, possible experiments are explained on color transparency and generalized parton distributions (GPDs). These projects are complementary to lepton-scattering experiments at JLab, COMPASS/AMBER, and future electron-ion colliders. Because of hadron-beam energies up to 30 GeV, the J-PARC is a unique facility to investigate the transition region from the hadron degrees of freedom to the quark-gluon one. It is suitable for finding mechanisms of the color transparency. Such color-transparency studies are also valuable for clarifying factorization of hadron-production processes in extracting the GPDs from actual measurements. These studies will lead to the understanding of basic high-energy hadron interactions in nuclear medium and to clarifications on the origins of hadron spins, masses, and internal pressure mechanisms.
