本文报道了顶夸克衰变为轻子和喷流的分支比的测量。用大型强子对撞机的ATLAS探测器记录了质心能量为7 TeV的碰撞事件。所采集的数据样本对应的积分光度为。测量到的顶夸克分支比与标准模型的预测在几个百分点的测量不确定性范围内一致。
Measurements of the branching ratios of top quark decays into leptons and jets using events with(top antitop) pairs are reported. Events were recorded with the ATLAS detector at the LHC incollisions at a center-of-mass energy of 7 TeV. The collected data sample corresponds to an integrated luminosity of. The measured top quark branching ratios agree with the Standard Model predictions within the measurement uncertainties of a few percent.
