Octet Quark Contents from SU(3) Flavor Symmetry

Abstract

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.
