横向性:理论与现象学

Transversity: theory and phenomenology

Umberto D'Alesio

摘要:

横向极化核子内部横向极化夸克的分布,称为横向性,编码了核子结构的基本信息,与更熟悉的非极化和螺旋分布具有相同的地位。我将回顾它的属性,并讨论访问它的不同方法,重点和限制。最近的现象学提取和观点也被提出。

英文摘要:

The distribution of transversely polarized quarks inside a transversely polarized nucleon, known as transversity, encodes a basic piece of information on the nucleon structure, sharing the same status with the more familiar unpolarized and helicity distributions. I will review its properties and discuss different ways to access it, with highlights and limitations. Recent phenomenological extractions and perspectives are also presented.
