Abstract
We present a measurement of the cross sections for the associated production of a W boson with at least one heavy quark jet, b or c, in proton–antiproton collisions. Data corresponding to an integrated luminosity of 8.7 fb−1 recorded with the D0 detector at the Fermilab Tevatron pp¯ Collider at s=1.96 TeV are used to measure the cross sections differentially as a function of the jet transverse momenta in the range 20 to 150 GeV. These results are compared to calculations of perturbative QCD theory as well as predictions from Monte Carlo generators.
Highlights
We present a measurement of the cross sections for the associated production of a W boson with at least one heavy quark jet, b or c, in proton–antiproton luminosity of 8.7 fb−1 recorded with the D0 detector collisions
The dominant processes contributing to W + c-jet production are qg → W c and qq → W g followed by g → cc
The production cross section for the first process is sensitive to the quark and gluon parton density functions (PDFs)
Summary
We present a measurement of the cross sections for the associated production of a W boson with at least one heavy quark jet, b or c, in proton–antiproton luminosity of 8.7 fb−1 recorded with the D0 detector collisions. 1.96 TeV are used to measure the cross sections differentially as a function of the jet transverse momenta in the range 20 to 150 GeV. Measurement of the p p → W + c-jet differential cross section should provide information about the s-quark PDF.
