部分子能级上的电荷对称性

Charge Symmetry at the Partonic Level

J. T. Londergan, J. C. Peng, A. W. Thomas

摘要:

这篇综述文章讨论了部分子电荷对称性的实验和理论状况。它示出了如何部分子内容的各种结构功能得到重新定义时,电荷对称性的假设放松。我们回顾了部分子分布函数中电荷对称性破坏的各种理论和唯象模型。我们总结了目前部分子分布中电荷对称性破坏的实验上限。一系列的实验,这可能会揭示部分子电荷对称性破坏,或者可能会降低目前的上限部分子电荷对称性破坏。

英文摘要:

This review article discusses the experimental and theoretical status of partonic charge symmetry. It is shown how the partonic content of various structure functions gets redefined when the assumption of charge symmetry is relaxed. We review various theoretical and phenomenological models for charge symmetry violation in parton distribution functions. We summarize the current experimental upper limits on charge symmetry violation in parton distributions. A series of experiments are presented, which might reveal partonic charge symmetry violation, or alternatively might lower the current upper limits on parton charge symmetry violation.
