标题： Progress in Top Quark Physics

摘要： 顶夸克性质的实验测量正在改进，并且将在未来几年显著改善，这得益于费米国家加速器实验室中的 CDF 和 D0 实验以及 Tevatron $p\bar{p}$ 对撞机的出色运行。 所有与顶夸克产生和衰变相关的最终态实验信号都被用来检验这种最重的夸克是否对标准模型之外的新物理敏感。 到目前为止，观测结果与标准模型一致。 新的技术手段大幅提高了顶夸克质量测量的精确度至 1.7%，并为在 2008 年实现小于 1% 的测量精度奠定了基础。 对顶夸克质量的这一更精确的知识，能够更加锐化标准模型对尚未发现的希格斯玻色子质量的预测，这对未来 LHC 和 ILC 的希格斯粒子研究具有重要意义。 显示英文摘要

摘要： Experimental measurements of the properties of the top quark have improved and will continue to improve significantly, with the excellent operation of the CDF and D0 experiments and the Tevatron $p\bar{p}$ collider at the Fermi National Accelerator Laboratory. All of the final state experimental signatures from top quark production and decay are being analysed to test if this most massive quark is sensitive to new physics beyond the standard model. So far, observations are consistent with the standard model. New techniques have dramatically improved the precision of the top quark mass measurement to 1.7% and set the stage for a sub-1% measurement by 2008. This improved knowledge of the top quark mass sharpens the standard model prediction for the mass of the undiscovered Higgs boson, with implications for Higgs studies at the future LHC and ILC.
