关于氘的相对论电荷分布

On the deuteron relativistic charge distributions

Cédric Lorcé, Pierre Wang

摘要:

研究了自旋$1$靶的相对论二维电荷分布。这些电荷分布是基于相空间的方法,使人们能够研究它们的帧依赖性,因此,与熟悉的休息帧图片与光前图片在过去的二十年中开发的。像在自旋- $1/2$的情况下,我们表明,相对论运动学效应与自旋是负责在移动框架中看到的电荷分布的扭曲。将我们的结果应用于氘核,我们观察到一个温和的框架依赖相比,核子的情况。

英文摘要:

We study the relativistic 2D charge distributions in the case of a spin-$1$ target. These charge distributions are based on a phase-space approach allowing one to study their frame dependence, and hence to relate the familiar rest-frame picture with the light-front picture developed in the last two decades. Like in the spin-$1/2$ case, we show that relativistic kinematical effects associated with spin are responsible for the distortions of the charge distributions seen in a moving frame. Applying our results to the deuteron, we observe a mild frame dependence compared to the nucleon case.
