SU的八重态夸克含量(3)味对称性

Octet Quark Contents from SU(3) Flavor Symmetry

Haitao Liu, Yujie Chi, Lijing Shao, Bo-Qiang Ma

摘要:

利用Soffer \textit{et al.}参数化质子的部分子分布函数,利用SU(3)味对称性将价夸克含量推广到其它八重态重子.我们发现这个方法实际上很有用。碎裂函数(FFs)进一步通过在$x \to 1$区域的唯象Gribov-Lipatov关系获得。我们的结果与不同的模型进行了比较,这些不同的预测可以区分即将进行的实验。

英文摘要:

With the parametrization of parton distribution functions (PDFs) of the proton by Soffer \textit{et al.}, we extend the valence quark contents to other octet baryons by utilizing SU(3) flavor symmetry. We find the method practically useful. Fragmentation functions (FFs) are further obtained through the phenomenological Gribov-Lipatov relation at the $x \to 1$ region. Our results are compared with different models, and these different predictions can be discriminated by upcoming experiments.
