摘要：

在超对称性搜索中，对事件中缺失的横向能量的观测和测量是一个关键的特征。本文介绍了ATLAS中缺失横向能量的重建和标定，并讨论了各种模拟过程中的测量质量，这些过程包括物理缺失横向能量的$Z$ $\to$ $τ^{+}τ^{-}$，$A^{0}$ / $H^{0}$ $\to$ $τ^{+}τ^{-}$，$t$ $\bar{t}$和SUSY，以及不包含缺失横向能量的过程，如最小偏差和$Z$ +喷流。期望使用早期的数据在评估中的测量丢失的横向能量。

英文摘要：

The observation and measurement of missing transverse energy in an event is a key signature in SUSY searches. This paper describes the reconstruction and calibration of missing transverse energy in ATLAS, and addresses the quality of the measurement in a variety of simulated processes which contain physical missing transverse energy such as $Z$ $\to$ $τ^{+}τ^{-}$, $A^{0}$ / $H^{0}$ $\to$ $τ^{+}τ^{-}$, $t$$\bar{t}$, and SUSY as well as processes which contain no missing transverse energy such as minimum bias and $Z$+jets. Expectations for the use of early data in evaluation of the measurement of missing transverse energy are presented.
