Associated 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 کاملW + 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 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...
متن کاملElectromagnetic production of quarkonium in Z0 decay.
The decay Z → Q+ ll, where Q is a J = 1 quarkonium state, has a very clean final state, which should make it easy to detect. The branching ratio of this mode is greater than 10 for ρ, φ, and ψ, indicating that these processes may be detectable at LEP. Well over one million Z decay events have been accumulated at LEP, and further improvements are expected. This makes it possible to investigate r...
