横贯性

Transversity

Umberto D'Alesio

摘要:

横度分布与非极化分布和螺旋度分布一起,代表了核子内部结构的基本信息。它是奇手性量的独特性质意味着它只能与另一个奇手性伙伴结合才能获得,这使得测量变得更加困难。在这次演讲中,我将回顾它的属性,并描述最相关和最可行的方法来访问它。最近的现象学提取,他们的亮点和局限性,以及前景进行了讨论。

英文摘要:

Transversity distribution, together with the unpolarized and the helicity distributions, represents a basic piece of information on the internal structure of nucleons. Its peculiar property of being a chiral-odd quantity implies that it can be accessed only in combination with another chiral-odd partner, making it much harder to measure. In this talk I will review its properties and describe the most relevant and feasible ways to access it. Recent phenomenological extractions, their highlights and limitations, as well as perspectives are discussed.
