顶夸克质量的精确测定

Precision Determination of the Top Quark Mass

Pedro A. Movilla Fernandez

摘要:

CDF和D 0合作更新了他们使用Tevatron产生的sqrt{s}=1.96TeV的质子-反质子碰撞测量顶夸克质量的方法。在每个顶-反顶衰变通道的不确定性已被降低。根据每次实验大约1/fb的数据,新的Tevatron平均顶夸克质量为170.9+-1.8GeV/c^2。

英文摘要:

The CDF and D0 collaborations have updated their measurements of the mass of the top quark using proton-antiproton collisions at sqrt{s}=1.96TeV produced at the Tevatron. The uncertainties in each of the of top-antitop decay channels have been reduced. The new Tevatron average for the mass of the top quark based on about 1/fb of data per experiment is 170.9+-1.8GeV/c^2.
