| Summary: | The measurement of the missing transverse energy (ETmiss ) is fundamental for many analyses at LHC. Good ETmiss resolution and calibration are essential for searches of new physics as well as precise measurements. We describe a refined reconstruction and calibration of ETmiss developed by ATLAS and its performances on events containing Z and W bosons. The data sample was collected in proton-proton collisions at a center-of-mass energy of 7 TeV, and corresponds to an integrated luminosity of about 36 pb−1. The determination of the absolute scale of the ETmiss , fundamental for determining systematic uncertainties in all analysis involving ETmiss measurements, is also presented. |
