核子结构的模型无关结果

Model independent results for nucleon structure

Gerald A Miller

摘要:

我回顾最近的结果,核子电荷和磁化强度密度以及形状的核子。首先,一些唯象的考虑,表明质子的形状是不是圆的进行了讨论。然后模型无关的结果,关于中子和质子的电荷密度,和质子磁化强度密度。最后,我展示了如何自旋相关的密度,揭示了质子的形状可以通过它们与横向动量分布的关系来测量。目前的工作是可能的,最近在贝茨,美因茨和杰斐逊实验室取得了巨大的实验进展。

英文摘要:

I review recent results regarding the nucleon charge and magnetization densities as well as the shape of the nucleon. First, some phenomenolgical considerations that show that the shape of the proton is not round are discussed. Then model independent results regarding the neutron and proton charge density, and the proton magnetization density are presented. Finally, I show how the spin-dependent densities that reveal the shape of the proton can be measured via their relation with transverse momentum distributions. The present work is made possible by the recent tremendous experimental progress made at Bates, Mainz and Jefferson Laboratory.
