Abstract:

We present a measurement of the inclusive jet cross section using the Run II cone algorithm and data collected by the D0 experiment in pp̄ collisions at a center-of-mass energy √s=1.96TeV, corresponding to an integrated luminosity of 0.70fb -1. The jet energy calibration and the method used to extract the inclusive jet cross section are described. We discuss the main uncertainties, which are dominated by the jet energy scale uncertainty. The results cover jet transverse momenta from 50GeV to 600GeV with jet rapidities in the range -2.4 to 2.4 and are compared to predictions using recent proton parton distribution functions. Studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented. © 2012 American Physical Society.

Abstract:

In this Letter, we present a precise measurement of the total ZZ production cross section in pp̄ collisions at √s=1.96TeV, using data collected with the CDF II detector corresponding to an integrated luminosity of approximately 6fb-1. The result is obtained by combining separate measurements in the four-charged (′′) and two-charged-lepton and two-neutral-lepton (νν) decay modes of the Z boson pair. The combined measured cross section for pp̄→ZZ is 1.64-0.38+0.44pb. This is the most precise measurement of the ZZ production cross section in 1.96 TeV pp̄ collisions to date. © 2012 American Physical Society.

Abstract:

We present a search for the standard model Higgs boson production in association with a W boson in proton-antiproton collisions (pp̄→W ±H→νbb̄) at a center of mass energy of 1.96 TeV. The search employs data collected with the CDF II detector which correspond to an integrated luminosity of approximately 2.7fb -1. We recorded this data with two kinds of triggers. The first kind required high-p T charged leptons and the second required both missing transverse energy and jets. The search selects events consistent with a signature of a single lepton (e ±/μ ±), missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with a secondary vertex tagging method and a jet probability tagging method. Kinematic information is fed in an artificial neural network to improve discrimination between signal and background. The search finds that both the observed number of events and the neural network output distributions are consistent with the standard model background expectations, and sets 95% confidence level upper limits on the production cross section times branching ratio. The limits are expressed as a ratio to the standard model production rate. The limits range from 3.6 (4.3 expected) to 61.1 (43.2 expected) for Higgs masses from 100 to 150GeV/c2, respectively. © 2012 American Physical Society.
