Abstract:

We report a new measurement of the cross section for the production of isolated photons with transverse energies (E Tγ) above 10 GeV and pseudorapidities |η| < 2.5 in p̄ collisions at √s = 1.8 TeV. The results are based on a data sample of 107.6 pb -1 recorded during 1992-1995 with the D0 detector at the Fermilab Tevatron collider. The background, predominantly from jets which fragment to neutral mesons, was estimated using the longitudinal shower shape of photon candidates in the calorimeter. The measured cross section is in good agreement with the next-to-leading order QCD calculation for E Tγ ≳ 36 GeV. © 2000 The American Physical Society.

Abstract:

The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter presents a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behaviour is obtained. The underlying radial energy densities for the four depth segments and for the entire calorimeter have been reconstructed. A three-dimensional hadronic shower parametrization has been developed. The results presented here are useful for understanding the performance of iron-scintillator calorimeters, for developing fast simulations of hadronic showers, for many calorimetry problems requiring the integration of a shower energy deposition in a volume and for future calorimeters design.

Abstract:

We present a measurement of the differential cross section as a function of transverse momentum of the Z boson in pp̄ collisions at √s=1.8 TeV using data collected by the DØ experiment at the Fermilab Tevatron Collider during 1994-1996. We find good agreement between our data and the next-to-next-to-next-leading-logarithmic resummation prediction and extract values of the non-perturbative parameters for the resummed prediction from a fit to the differential cross section. ©2000 The American Physical Society.

Cross section for b-jet production in supp^¯p collisions at √s=1.8 TeV

Abstract:

Bottom-quark production in p¯p collisions at √s=1.8 TeV is studied with 5 pb−1 of data collected in 1995 by the D0 detector at the Fermilab Tevatron Collider. The differential production cross section for b jets in the central rapidity region (|yb|<1) as a function of jet transverse energy is extracted from a muon-tagged jet sample. Within experimental and theoretical uncertainties, D0 results are found to be higher than, but compatible with, next-to-leading-order QCD predictions. © 2000 The American Physical Society.
