Resumen:
The measurement of missing transverse momentum in the
ATLAS detector, described in this paper, makes use of the full event
reconstruction and a calibration based on reconstructed physics objects.
The performance of the missing transverse momentum reconstruction is
evaluated using data collected in pp collisions at a centre-of-mass
energy of 7 TeV in 2010. Minimum bias events and events with jets of
hadrons are used from data samples corresponding to an integrated
luminosity of about 0.3 inverse nb and 600 inverse nb, together with
events containing a Z boson decaying to two leptons (electrons or muons)
or a W boson decaying to a lepton (electron or muon) and a neutrino,
from a data sample corresponding to an integrated luminosity of about 36
inverse pb. An estimate of the systematic uncertainty on the missing
transverse momentum scale is presented.
