核子海中夸克与反夸克不对称性及其检验

Researched on the spin structure of the hyperons, and predicted the fragmentation functions of hyperons based on the relation between the structure functions and fragmentation functions. Suggested physical processes to measure the spin structure of hyperons. The strange content and flavor asymmetry of the nucleon sea are also investigated.

核子的夸克自旋和味道结构为当前粒子物理和核物理界关注的前沿领域。本项目旨在研究核子内夸克与反夸克不对称的理论依据和可能的实验迹象，及与这种不对称性有关的各种物理问题。将细致研究核子内奇异夸克动量和自旋分布的测量过程，夸克到强子的碎裂过称，不对称性的实验检验及有关理论问题，与核子内奇异和其它味道夸克有关的物理问题等。
