Abstract A precise determination of the energy scale of jets at the Collider Detector at Fermilab at the Tevatron p p ¯ collider is described. Jets are used in many analyses to estimate the energies of partons resulting from the underlying physics process. Several correction factors are developed to estimate the original parton energy from the observed jet energy in the calorimeter. The jet energy response is compared between data and Monte Carlo simulation for various physics processes, and systematic uncertainties on the jet energy scale are determined. For jets with transverse momenta above 50 GeV the jet energy scale is determined with a 3 % systematic uncertainty.

Determination of Jet Energy Calibration and Transverse Momentum Resolution in CMS (2011, methodology): “The technique was introduced at the CERN pp̄ collider (SPP̄S) [12] and later refined by the Tevatron experiments [13, 14].”
Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV (2016, methodology): “The minimum JES uncertainty of 0.32% for jets with 165 pT 330 GeV and |η| 0.8, when excluding sample-dependent uncertainties due to jet-flavor response and time-dependent detector response variations, surpasses the precision of previous JES measurements at the Tevatron [15, 16] and the LHC [13”

Non-perturbative QCD effects in jets at hadron colliders (2007, background): “5, using our analytical results for the perturbative and for the two non-perturbative contributions, for 50GeV quark jets, with the normalisation for the underlying event contribution set to ΛUE = 4GeV, corresponding roughly to Pythia’s estimate for the Tevatron.”

The Catchment Area of Jets (2008, result): “This shows that the cone area is very sensitive to the structure of the event, and it certainly does not always coincide with the naive geometrical expectation πR2, contrary to assumptions sometimes made in the literature (see for example [25]).”
Hard photon production and matrix-element parton-shower merging (2009, background): “Less spectacular but extremely important though, photon + jet final state can be used to determine the absolute energy scale of low-pT jets [3] and to constrain the gluon distribution inside the beam hadron [4].”
