“…The calorimeter consists of uranium-liquid argon sampling detectors with fine segmentation in a central and two end cryostats, and provides near-hermetic coverage for |η| ≤ 4.4. The energy resolution of the calorimeter was measured in beam tests [6] to be 15%/ √ E for electrons and 50%/ √ E for isolated pions (E in GeV). The calorimeter towers subtend 0.1 × 0.1 in η × φ (φ is the azimuthal angle), segmented longitudinally into four electromagnetic (EM) and four or five hadronic layers.…”

“…Fluctuations cause the energy deposition to vary from the average in a correlated fashion among the cells and layers. Longitudinal and transverse shower shapes, and the correlations between energy depositions in the calorimeter cells are taken into account to obtain the best discrimination against hadrons, using a covariance matrix ("H-matrix") technique [12,13]. A covariance matrix is formed from a set of eight well-modeled variables describing shower shapes:…”

The electron and photon reconstruction and identification algorithms used by the D0 Collaboration at the Fermilab Tevatron collider are described. The determination of the electron energy scale and resolution is presented. Studies of the performance of the electron and photon reconstruction and identification are summarized. The results are based on measurements of Z boson decay events of Z → ee and Z → γℓℓ (ℓ = e, µ) collected in pp collisions at a center-of-mass energy of 1.96 TeV using an integrated luminosity of up to 10 fb −1 .

Energy flow in a hadronic cascade: Application to hadron calorimetry

The hadronic cascade description developed in an earlier paper is extended to the response of an idealized fine-sampling hadron calorimeter. Calorimeter response is largely determined by the transfer of energy E π 0 from the hadronic to the electromagnetic sector via π 0 production. Fluctuations in this quantity produce the "constant term" in hadron calorimeter resolution. The increase of its fractional mean, f 0 π 0 = E π 0 /E, with increasing incident energy E causes the energy dependence of the π/e ratio in a noncompensating calorimeter. The mean hadronic energy fraction, f 0 h = 1 − f 0 π 0 , was shown to scale very nearly as a power law in E: f 0 h = (E/E 0 ) m−1 , where E 0 ≈ 1 GeV for pions, and m ≈ 0.83. It follows that π/e = 1 − (1 − h/e)(E/E 0 ) m−1 , where electromagnetic and hadronic energy deposits are detected with efficiencies e and h, respectively. If the mean fraction of f 0 h which is deposited as nuclear gamma rays is f 0 γ , then the expression becomes π/e = 1 − (1 − h ′ /e)(1 − f 0 γ )(E/E 0 ) m−1 . Fluctuations in these quantities, along with sampling fluctuations, are incorporated to give an overall understanding of resolution, which is different from the usual treatments in interesting ways. The conceptual framework is also extended to the response to jets and the difference between π and p response.
