摘要

ATLAS实验中的光度测量主要由LUCID探测器提供，但依赖于其他探测器来确定与此测量相关的系统不确定度。作为ATLAS实验中心强子量热计的Tile量热计(TileCal)和ATLAS内部探测器(ID)由于其光度测量不受堆积的影响而发挥了重要作用。将不同运行条件下的LUCID光度测量值与TileCal和ID测量值进行比较，并将TileCal与ID进行比较，用于测量和研究与LUCID光度测量相关的主要系统不确定度。本文描述了用瓦式量热计测量ATLAS光度的方法及其向系统不确定度的转换。

Measurements of Luminosity in ATLAS with Tile Calorimeter

Luminosity measurements in the ATLAS experiment are provided primarily by the LUCID detector, but rely on other detectors for determining the systematic uncertainties associated with this measurement. The Tile Calorimeter (TileCal), the central hadronic calorimeter of the ATLAS experiment, and the ATLAS Inner Detector (ID) play an important role due to their luminosity measurements being independent of pileup. Comparison of the LUCID luminosity measurements in different run conditions to those obtained by TileCal and ID, as well as a comparison of TileCal to ID, is used to measure and study the dominant systematic uncertainty associated with the LUCID luminosity measurement. In this document the methods of measuring ATLAS luminosity with the Tile Calorimeter and its transformation to a systematic uncertainty are described.
