Query: The performance of the jet trigger for the ATLAS detector during 2011
  data taking   The performance of the jet trigger for the ATLAS detector at the LHC during
the 2011 data taking period is described. During 2011 the LHC provided
proton-proton collisions with a centre-of-mass energy of 7 TeV and heavy ion
collisions with a 2.76 TeV per nucleon-nucleon collision energy. The ATLAS
trigger is a three level system designed to reduce the rate of events from the
40 MHz nominal maximum bunch crossing rate to the approximate 400 Hz which can
be written to offline storage. The ATLAS jet trigger is the primary means for
the online selection of events containing jets. Events are accepted by the
trigger if they contain one or more jets above some transverse energy
threshold. During 2011 data taking the jet trigger was fully efficient for jets
with transverse energy above 25 GeV for triggers seeded randomly at Level 1.
For triggers which require a jet to be identified at each of the three trigger
levels, full efficiency is reached for offline jets with transverse energy
above 60 GeV. Jets reconstructed in the Event Filter and corresponding to
offline jets with transverse energy greater than 60 GeV, are reconstructed with
a resolution in transverse energy of better than 4% in the central region and
better than 2.5% in the forward direction.
