来自ATLAS的最新QCD成绩

Recent QCD Results from ATLAS

Chris Meyer

摘要:

本文介绍了在7TeV质心能量下利用大型强子对撞机(LHC)进行的ATLAS实验的QCD结果,包括:双喷注产生、孤立光子产生、与喷注有关的孤立光子产生、顶夸克对事件中的喷注形状、phi(1020)介子的产生截面以及喷注事件中的基础事件。良好的协议与理论预测,特别是与下一个领先的顺序发电机。这些测量突出了精确QCD测量对于改进最先进的理论工具和寻找新物理的重要性。

英文摘要:

Recent QCD results from ATLAS taken at 7 TeV center-of-mass energy using the LHC are presented, including: dijet production, isolated photon production, isolated photon production associated with jets, jet shapes in top-quark pair events, the production cross-section of the phi(1020) meson, and underlying event in jet events. Good agreement with theory predictions is seen, in particular with those made by next-to-leading-order generators. These measurements highlight the importance of precision QCD measurements for improving state-of-the-art theoretical tools and searching for new physics.
