杰斐逊实验室的非极化结构函数

Unpolarized structure functions at Jefferson Lab

M. E. Christy, W. Melnitchouk

摘要:

在过去的十年中,杰斐逊实验室以前所未有的精度对非极化结构函数进行了测量,大大提高了我们对核子结构的认识。这是第一次允许定量测试的现象,夸克强子的二重性,并提供了一个更深入的了解从强子到夸克的过渡自由度的包容性散射。专门的Rosenbluth分离实验已经在以前未探索的区域产生了高精度的横向和纵向结构函数,新技术使人们能够首次瞥见自由中子的结构,而不会受到核效应的污染。

英文摘要:

Over the past decade measurements of unpolarized structure functions at Jefferson Lab with unprecedented precision have significantly advanced our knowledge of nucleon structure. These have for the first time allowed quantitative tests of the phenomenon of quark-hadron duality, and provided a deeper understanding of the transition from hadron to quark degrees of freedom in inclusive scattering. Dedicated Rosenbluth-separation experiments have yielded high-precision transverse and longitudinal structure functions in regions previously unexplored, and new techniques have enabled the first glimpses of the structure of the free neutron, without contamination from nuclear effects.
