Description
At the LHC, the Missing Transverse Energy (E_{T}^{miss}) is defined as the
transverse component of the energy of particles that do not leave any detectable signatures.
As such it is a vital component in many searches for SUSY or dark matter. In 2015, the
ATLAS detector collected good quality data corresponding to 3.21 fb^{1} of integrated
luminosity, which provides an excellent test of the performance of E_{T}^{miss}. In run 2, the
E_{T}^{miss} uses a track based soft term and calibrated preselected user defined hard
objects. E_{T}^{miss} is studied in event topologies without real E_{T}^{miss}, such as
Z>\mu\mu/ee and with real E_{T}^{miss} such as W>e\nu_{e}/\mu\nu_{\mu}. The
distributions of E_{T}^{miss} and its components are compared between data and monte
carlo simulated signals/backgrounds. The E_{T}^{miss} diagnostics such as the scale,
resolution and response are shown.
