论文摘要
我们简要地报告了我们最近在低能量下的非极化半包含的深度无弹性散射和电子脉络膜歼灭的$λ$ Hyperon的偏振片段化函数的研究中的最新进展。特别是,我们提出了一种简单但实用的方法,讲述了如何测量依赖于角角的纵向极化以及生产平面内的横向极化,并将这些可观察到的物品桥接到相应的结构函数和领先扭曲处的碎片函数。我们的工作使可以探测两极分化碎片函数的高能量反应多样化。
We briefly report our recent progress on the study of the polarized fragmentation functions of $Λ$ hyperon in unpolarized semi-inclusive deep-inelastic scatterings and electron-positron annihilations at low energies. In particular, we present a simple but practical method on how to measure the azimuthal-angle-dependent longitudinal polarization and the transverse polarization inside the production plane and bridge these observables to the corresponding structure functions and fragmentation functions at the leading twist. Our work diversifies the high energy reactions that can probe the polarized fragmentation functions.
