Query: Performance of missing transverse momentum reconstruction in
  proton-proton collisions at 7 TeV with ATLAS   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.
