标题： Essential Strangeness in Nucleon Magnetic Moments

摘要： 从实验测量中提取的有效夸克磁矩是作为核子的奇异性磁矩的函数得到的。 甚至在最普遍的夸克模型分析中所做的假设也被这项研究排除了。 从头计算的量子色动力学（QCD）要求奇夸克在核子中扮演非平凡的角色。 对于质子的奇异性磁矩贡献为 0.11$\mu_N$的 QCD 计算得到的有效磁矩被重现，这对应于$F_2^s(0) = -0.33\ \mu_N$。 显示英文摘要

摘要： Effective quark magnetic moments are extracted from experimental measurements as a function of the strangeness magnetic moment of the nucleon. Assumptions made in even the most general quark model analyses are ruled out by this investigation. Ab initio QCD calculations demand a non-trivial role for strange quarks in the nucleon. The effective moments from QCD calculations are reproduced for a strangeness magnetic moment contribution to the proton of 0.11 $\mu_N$, which corresponds to $F_2^s(0) = -0.33\ \mu_N$.
