W + Jet Production at Cdf
The cross section for the inclusive production of W bosons in association with jets in pp̄ collisions at √ s = 1.96 TeV using the Collider Detector at Fermilab (CDF II) is presented. The measurement is based on an integrated luminosity of 320 pb, and includes events with up to 4 or more jets. In each jet multiplicity sample the differential and cumulative cross sections with respect to the trans...
متن کاملAssociated Production of a W Boson and One b Jet
We calculate the production of a W boson and a single b jet to next-to-leading order in QCD at the Fermilab Tevatron and the CERN Large Hadron Collider. Both exclusive and inclusive cross sections are presented. We separately consider the cross section for jets containing a single b quark and jets containing a bb̄ pair. There are a wide variety of processes that contribute, and it is necessary t...
متن کاملHiggs- and Z-boson production with a jet veto.
We derive first next-to-next-to-leading logarithmic resummations for jet-veto efficiencies in Higgs and Z-boson production at hadron colliders. Matching with next-to-next-to-leading order results allows us to provide a range of phenomenological predictions for the LHC, including cross-section results, detailed uncertainty estimates, and comparisons to current widely used tools.
متن کاملQuark masses in Higgs production with a jet veto
We study the impact of finite mass effects due to top and bottom loops in the jet-veto distribution for Higgs production. We discuss the appearance of non-factorizing logarithms in the region pt,veto & mb. We study their numerical impact and argue that these terms can be treated as a finite remainder. We therefore detail our prescription for resumming the jet-vetoed cross section and for assess...
متن کاملPrecise predictions for w+3 jet production at hadron colliders.
We report on the first next-to-leading order QCD computation of W+3-jet production in hadronic collisions including all partonic subprocesses. We compare the results with data from the Tevatron and find excellent agreement. The required one-loop matrix elements are computed using on-shell methods, implemented in a numerical program, BlackHat. We use the SHERPA package to generate the real-emiss...
