We investigate the quark spin content of the SU(3) baryon octet, decuplet, antitriplet, and sextet in a pion mean-field approach or the chiral quark-soliton model, considering the $1/N_c$ rotational corrections and SU(3) symmetry breaking effects. We compare the present results with those from various theoretical works and lattice QCD.

SU(3)轻重子和单重重子的夸克自旋含量

我们在π介子平均场方法或手性夸克-孤子模型中研究了 SU(3) 重子八位组、十重体、反三重体和六重体的夸克自旋含量，考虑到$1/{ñ}_C$旋转校正和 SU(3) 对称破坏效应。我们将目前的结果与各种理论工作和晶格 QCD 的结果进行比较。
