标题： Top-quark mass measurement in events with jets and missing transverse energy using the full CDF data set

摘要： 我们使用Tevatron $\sqrt{s} = 1.96$ TeV质子-反质子碰撞的完整数据集，由CDF II探测器记录，对应的积分亮度为 \invfb{8.7}。该分析使用包含一个半轻子 $t$ 或 $\bar{t}$ 衰变的事件，但未检测到电子或缪子。我们选择具有显著缺失横向能量和多个喷注的事件。我们排除包含已识别电子或缪子的事件。我们从数据中获得顶夸克质量以及来自 $W$-玻色子衰变的两个喷注的不变质量分布，并将这些与从信号和背景样本推导出的模板进行比较，以提取顶夸克质量以及量能器喷注的能量标度，采用 {\it 现场}校准。对信号和背景事件的模板进行似然拟合，得到顶夸克质量， $\mtop = \gevcc{\measStatSyst{173.93}{1.64}{0.87}}$。此结果是迄今为止在该事件拓扑结构中对顶夸克质量的最精确测量。 显示英文摘要

摘要： We present a measurement of the top-quark mass using the full data set of Tevatron $\sqrt{s} = 1.96$ TeV proton-antiproton collisions recorded by the CDF II detector, corresponding to an integrated luminosity of \invfb{8.7}. The analysis uses events with one semileptonic $t$ or $\bar{t}$ decay, but without detection of the electron or muon. We select events with significant missing transverse energy and multiple jets. We veto events containing identified electrons or muons. We obtain distributions of the top-quark masses and the invariant mass of the two jets from $W$-boson decays from data and compare these to templates derived from signal and background samples to extract the top-quark mass and the energy scale of the calorimeter jets with {\it in situ} calibration. A likelihood fit of the templates from signal and background events to the data yields the top-quark mass, $\mtop = \gevcc{\measStatSyst{173.93}{1.64}{0.87}}$. This result is the most precise measurement to date of the mass of the top quark in this event topology.
