标题： Not Strange but Bizarre Physics from the SAMPLE Experiment

摘要： 自SAMPLE合作组报告了关于奇夸克对核磁矩的贡献\( G_M^s(0) \)可能大于零以来，出现了许多支持正数值的模型。 本文阐述了与\( G_M^s(0) > 0 \)相关的奇异物理现象。 利用新的格点QCD结果，我们对\( G_M^s(0) \)的最佳估计从\( G_M^s(0) = -0.75 \pm 0.30 \mu_N \)略微调整为\( G_M^s(0) = -0.62 \pm 0.26 \mu_N \)。 显示英文摘要

摘要： Since the report of the SAMPLE Collaboration suggesting the strange-quark contribution to nucleon magnetic moments, G_M^s(0), may be greater than zero, numerous models have appeared supporting positive values for G_M^s(0). In this paper the bizarre physics associated with G_M^s(0) > 0 is illustrated. Using new lattice QCD results, our best estimate for G_M^s(0) shifts slightly from G_M^s(0) = -0.75 +/- 0.30 mu_N, to G_M^s(0) = -0.62 +/- 0.26 mu_N.
