论文摘要
引入了具有任意平均动量的目标的相对论电荷分布。它们提供了通常的Breit框架和无限摩托框架分布之间的插值。我们发现，可以从相位的角度将Breit框架分布解释为内部电荷的准密度，而无需任何相对论校正。我们还表明，BREIT框架和无限摩托框架分布之间的明显差异仅来自与自旋相关的运动伪像。
Relativistic charge distributions of targets with arbitrary average momentum are introduced. They provide an interpolation between the usual Breit frame and infinite-momentum frame distributions. We find that Breit frame distributions can be interpreted from a phase-space perspective as internal charge quasi-densities in the rest frame of a localized target, without any relativistic correction. We show also that the apparent discrepancies between Breit frame and infinite-momentum frame distributions simply result from kinematical artifacts associated with spin.
