双强子碎裂函数的横向性

The Dihadron fragmentation functions way to Transversity

A. Courtoy, Alessandro Bacchetta, Marco Radici

摘要:

基于对横向极化目标深度非弹性散射中π介子对产生的分析,给出了横向部分子分布的观测结果。这种提取依赖于从电子正电子湮没测量中获得的双强子碎裂函数的知识。这是首次尝试在共线分解的框架下确定的横向分布。

英文摘要:

Observations of the transversity parton distribution based on an analysis of pion-pair production in deep inelastic scattering off transversely polarized targets are presented. This extraction relies on the knowledge of dihadron fragmentation functions, which are obtained from electron-positron annihilation measurements. This is the first attempt to determine the transversity distribution in the framework of collinear factorization.
