论文摘要
提出了运行2期间LHC的Atlas检测器的发光度确定，并在$ \ sqrt {s} = 13 $ tev上$ pp $碰撞。绝对光度量表是在每年专用的运行期间使用范德梅尔光束分离扫描确定的，并使用来自几个亮度敏感探测器的互补测量来推断出物理学数据研究制度。每年的数据获取年份的综合亮度的总不确定性范围从0.9％到1.1％，并且在年之间部分相关。在标准数据质量选择之后，完整运行2 $ PP $数据样本对应于$ 140.1 \ pm 1.2 $ fb $^{ - 1} $的集成发光度，即0.83％的不确定性。分别分析了2017 - 18年度记录的针对精密标准模型物理测量值的低调数据的专用样本，并具有$ 338.1 \ pm 3.1 $ pb $^{ - 1} $的集成光度为$ 338.1 \ pm。
The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented, with $pp$ collisions at $\sqrt{s}=13$ TeV. The absolute luminosity scale is determined using van der Meer beam separation scans during dedicated running periods in each year, and extrapolated to the physics data-taking regime using complementary measurements from several luminosity-sensitive detectors. The total uncertainties in the integrated luminosities for each individual year of data-taking range from 0.9% to 1.1%, and are partially correlated between years. After standard data-quality selections, the full Run 2 $pp$ data sample corresponds to an integrated luminosity of $140.1\pm 1.2$ fb$^{-1}$, i.e. an uncertainty of 0.83%. A dedicated sample of low-pileup data recorded in 2017-18 for precision Standard Model physics measurements is analysed separately, and has an integrated luminosity of $338.1\pm 3.1$ pb$^{-1}$.
