Missing ET Performance in ATLAS

Abstract

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 $Z$ $\to$ ${\tau }^{+}{\tau }^{-}$, $A^0$ / $H^0$ $\to$ ${\tau }^{+}{\tau }^{-}$, $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.
