论文摘要
已通过深度虚拟的康普顿散射和两光片剂过程分别研究了在带电的 - 莱普顿散射和电子峰值碰撞中，已研究了空间般的和脉冲的广义分布（GPD）。此外，我们预计将来将进行强子加速器效率测量。 GPD将在阐明夸克和胶子方面阐明强子旋转和质量的起源方面发挥关键作用。也可以探测哈子内部压力以理解其稳定性。曾经被认为是纯粹学术的主题的哈德子的重力形式因素，因为重力相互作用太弱，无法在微观系统中测量。但是，由于强子 - 体-摄影场的发展，因此可以从实际的GPD测量值中提取重力形式，而不依赖于直接重力相互作用。将来也可以使用中微子反应用于GPD研究，例如，通过使用Fermilab的长基线中微子设施。中微子GPD的测量值是有价值的，特别是对于以互补的方式找到GPD的风味依赖性。我们提供了GPD的概述，并使用单杆型生产过程$ν + n \ to \ ell^ - + n' +π$和$ \barν + n \ to \ ell^ + + + n' +π$讨论了可能的中微子GPD测量值。
Spacelike and timelike generalized parton distributions (GPDs) have been investigated in charged-lepton scattering and electron-positron collisions via deeply virtual Compton scattering and two-photon processes, respectively. Furthermore, we expect that hadron-accelerator-facility measurements will be performed in future. The GPDs will play a crucial role in clarifying the origins of hadron spins and masses in terms of quarks and gluons. It is also possible to probe internal pressure within hadrons for understanding their stability. Gravitational form factors of hadrons used to be considered as a purely academic subject because gravitational interactions are too weak to be measured in microscopic systems. However, due to the development of hadron-tomography field, it became possible to extract the gravitational form factors from the actual GPD measurements without relying on direct gravitational interactions. Neutrino reactions can also be used for GPD studies in future, for example, by using the Long-Baseline Neutrino Facility at Fermilab. The neutrino GPD measurements are valuable especially for finding the flavor dependence of the GPDs in a complementary way to the charged-lepton experiments. We give an overview of the GPDs and discuss possible neutrino GPD measurements using the single-pion production processes $ν+ N \to \ell^- + N' + π$ and $\barν+ N \to \ell^+ + N' + π$.
