论文摘要
极化的奇怪的夸克难题是一个事实，即从极化的含有的深层无弹性散射数据中提取的两极化奇怪的夸克密度显着为负，而从对极化半熟悉和包容性深度弹性数据的组合分析中提取时，它是零或略有正的。 SU（3）风味对称性，通常被接受，不是确切的对称性，在包容性分析中起着重要作用，并且所有提取的极化夸克密度在某种程度上取决于引入的对称性破坏水平。但是到目前为止，对破裂最敏感的是奇怪的夸克密度。在本文中，我们介绍了有关质子，中子和杜特子的极化包含数据数据的NLO QCD分析，包括有关质子和迪特龙的最终JLAB CLAS/EG1B数据，并研究了奇怪的Quark偏振对风味SU的破裂的敏感性（3）。
The polarized strange quark puzzle concerns the fact that the polarized strange quark density extracted from polarized inclusive deep inelastic scattering data is significantly negative, whereas it is zero or slightly positive when extracted from a combined analysis of polarized semi-inclusive and inclusive deep inelastic data. SU(3) flavor symmetry, which, it is generally accepted, is not an exact symmetry, plays an important role in the inclusive analysis, and all the extracted polarized quark densities depend, to some extent, on the level of symmetry breaking introduced. But by far the most sensitive to the breaking is the strange quark density. In this paper we present a NLO QCD analysis of the world data on polarized inclusive DIS data on protons, neutrons and deuterons, including the final JLAB CLAS/EG1b data on the proton and deuteron, and study the sensitivity of the strange quark polarization to the breaking of flavor SU(3).
