- "Observation of the single top quark production is an important milestone for the Tevatron program," said Dr. 此前，顶夸克只是在强核力产生时才能观察到，这种相互作用可导致产生一对顶夸克。
- CDF collaboration has observed the evidence of top quark in 1. 8 TeV pp collisions, on the Tevatron at Fermi National Lab. 美国费米国家实验室的CDF实验组在对撞能量1.;8 GeV的TEVATRON质子-反质子对撞机上观察到了顶夸克的证据。
- By fitting electromagnetic form factor data of nucleon with theVDM and quark theory, toponium mass and top quark mass areestimated. 本文应用VDM模型和夸克理论拟合核子电磁形状因子实验数据,估算了顶夸克偶素的质量和顶夸克质量。
- Discovering the single top quark production presents challenges similar to the Higgs boson search in the need to extract an extremely small signal from a very large background. 发现单顶夸克的难度并不亚于寻找希格斯玻色子，需要从很大的背景中提取一个极小的信号。
- For example, the analysis of precision measurements of W and Z boson properties led to the accurate prediction of the top quark mass before the top quark had been directly produced. 举个例子，在以实验直接制造出顶夸克之前，我们就已经藉由分析W与Z玻色子相关性质的精密测量，而精准预测出顶夸克的质量。
- It predicted the existence of the W and Z bosons, the gluon and two of the heavier quarks (the charm and the top quark). 它预测了W玻色子、Z玻色子、胶子以及两种较重的夸克（魅、顶夸克）。

- The observation of the production of single top quarks (rather than the easier-to-see production of top-antitop quark pairs) has been a goal of the Tevatron experiments for years. 然而，使用这种思路来解决现在数码产品的供电问题可能没什么前途，因为人体能够提供的能量并不能算大，而且转换效率也不算高。
- Our confidence in this procedure is bolstered because a similar approach accurately predicted the top quark mass before any top quarks had been detected directly. 在找到顶夸克之前，类似的计算也精确地预测了它的质量，所以我们对这种预测的方法有信心。
