摘要:

最近,杰斐逊实验室利用自旋观测量对质子和中子形状因子进行了精确的测量,对揭开核子的内部结构做出了重大贡献。核子形状因子的精确实验测量是理解核子的静态性质和动力学行为如何从QCD(夸克之间的强相互作用理论)中出现的测试平台。自从杰斐逊实验室公布了质子形状因子比数据以来,在重新评估核子图像方面取得了巨大的理论进展。我们将回顾这一领域的实验和理论发展,并讨论未来的展望。

英文摘要:

Precise proton and neutron form factor measurements at Jefferson Lab, using spin observables, have recently made a significant contribution to the unraveling of the internal structure of the nucleon. Accurate experimental measurements of the nucleon form factors are a test-bed for understanding how the nucleon's static properties and dynamical behavior emerge from QCD, the theory of the strong interactions between quarks. There has been enormous theoretical progress, since the publication of the Jefferson Lab proton form factor ratio data, aiming at reevaluating the picture of the nucleon. We will review the experimental and theoretical developments in this field and discuss the outlook for the future.
