横向电荷密度

Transverse Charge Densities

Gerald A. Miller

摘要:

电磁形状因子长期以来一直被用来探测强子和原子核的基本电荷和磁化密度。传统的三维傅里叶变换方法不严格适用于具有相对论运动的组分的系统。横向电荷密度是分析强子电磁形状因子的一种新的、严格定义的方法。本文综述了横向电荷密度的定义、如何从弹性散射数据中提取横向电荷密度、现有的结果、与其它可观测量的关系以及未来的展望。

英文摘要:

Electromagnetic form factors have long been used to probe the underlying charge and magnetization densities of hadrons and nuclei. Traditional three-dimensional Fourier transform methods are not rigorously applicable for systems with constituents that move relativistically. The use of the transverse charge density is a new, rigorously defined way to analyze electromagnetic form factors of hadrons.This review is concerned with the following issues: what is a transverse charge density; how is one extracted one from elastic scattering data; the existing results; what is the relationship with other observable quantities; and, future prospects.
