Abstract:

We present a measurement of the transverse momentum distribution of Z bosons produced in pp collisions at √s = 1.8 TeV from data collected by the D experiment at the Fermilab Tevatron Collider. We find good agreement between our results and current resummation calculations, and also use our data to extract nonperturbative parameters for a particular version of the resummation formalism. The resulting values are significantly more precise than obtained in previous determinations. © 2000 The American Physical Society.

Abstract:

We report a new measurement of the cross section for the production of isolated photons with transverse energies (E T ^γ) 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 T ^γ ≳ 36 GeV. © 2000 The American Physical Society.

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.
