横向部分分布

Transversity Parton Distribution

Alexei Prokudin

摘要:

横观分布是完整描述极化自旋1/2核子的三种基本部分子分布之一。它的手性奇性多年来阻碍了它的实验探索,然而目前我们已经获得了大量关于这种分布的信息。这包括半包容性深非弹性散射的实验数据,尺度依赖性和唯象提取的知识。我将讨论这个分布的主要特征,并指出我们知识的未来改进。

英文摘要:

Transversity distribution is one of the three fundamental parton distributions that completely describe polarized spin 1/2 nucleon. Its chiral odd nature prevented for many years its experimental exploration, however presently we have obtained great deal of information about this distribution. This includes experimental data from Semi Inclusive Deep Inelastic Scattering, knowledge of scale dependence and phenomenological extractions. I will discuss main features of this distribution and indicate the future improvements of our knowledge.
