结合CDF和DO计算顶夸克的质量

Combination of CDF and DO results on the mass of the top quark using up to 5.8~fb-1 of data

Tevatron Electroweak Working Group, CDF, D0 Collaborations

摘要:

我们总结了费米实验室的CDF和DO实验的顶夸克质量测量。我们结合公布的运行I(1992- 1996年)的测量与最精确的公布和初步运行II(2001年至今)的测量使用高达5.8 fb-1的数据,增加新的分析(Met+Jets分析)和更新旧的。考虑到不确定性相关,并将统计和系统不确定性进行正交相加,得到的顶夸克的初始Tevatron平均质量为M_T=173.2+/-0.9 GeV/c^2。

英文摘要:

We summarize the top-quark mass measurements from the CDF and DO experiments at Fermilab. We combine published Run I (1992--1996) measurements with the most precise published and preliminary Run II (2001-present) measurements using up to 5.8 fb-1 of data, adding new analyses (the Met+Jets analysis) and updating old ones. Taking uncertainty correlations into account, and adding in quadrature the statistical and systematic uncertainties, the resulting preliminary Tevatron average mass of the top quark is M_T=173.2+/-0.9 GeV/c^2.
