The production of a W boson and two jets, at least one of which contains a b quark, is a principal background to single-top production, Higgs production, and signals of new physics at hadron colliders. We present a next-to-leading-order…
The leading-order process for the production of a Z boson and a heavy-quark jet at hadron colliders is gQ -> ZQ (Q=c,b). We calculate this cross section at next-to-leading order at the Tevatron and the LHC, and compare it with other sources…
We present a next-to-leading-order calculation of the production of a Z boson with two jets, one or more of which contains a heavy quark (Q=c,b). We show that the cross section with only one heavy-quark jet is larger than that with two…
We present the next-to-leading order QCD corrections to the production of a $W$-boson in association with a jet containing a heavy quark. The calculation is fully differential in the final state particle momenta and includes the mass of the…
The production of both charged and neutral electroweak gauge bosons in association with $b$ jets has attracted a lot of experimental and theoretical attention in recent years because of its central role in the physics programs of both the…
The next-to-leading order QCD corrections to the production of a $W$-boson in association with a jet containing a heavy quark are presented. The calculation is fully differential in the final state particle momenta and includes the mass of…
We present total and differential cross sections for W b anti-b and Z b anti-b production at the CERN Large Hadron Collider including Next-to-Leading Order (NLO) QCD corrections and full bottom-quark mass effects. We discuss the scale…
We calculate the production of a W boson in association with up to two jets including at least one b-jet to next-to-leading order (NLO) in QCD at the CERN Large Hadron Collider with 7 TeV center-of-mass energy. Both exclusive and inclusive…
In this talk we give a short review of forward jets and forward $W$-boson production at hadron colliders, in view of the extraction of footprints of BFKL physics. We argue that at Tevatron energies, dijet production at large rapidity…
We report on the calculation of the next-to-leading order QCD corrections to the production of W-boson pairs in association with a hard jet at the Tevatron and the LHC, which is an important source of background for Higgs and new-physics…
We report on application of QCD in calculations of forward jet and W, Z boson production cross sections at the Large Hadron Collider. In particular in case of jet production we emphasize dynamical features of the matrix elements controlling…
The cross section for jets from b quarks produced with a W boson has been measured in ppbar collision data from 1.9/fb of integrated luminosity recorded by the CDF II detector at the Tevatron. The W+b-jets process poses a significant…
We analyse W boson production at hadron colliders in association with one or two jets, both with the exact kinematics and in the high-energy limit. We argue that the configurations that are kinematically favoured tend to have the W boson…
The associated production of jets and vector bosons is an important process at hadron colliders. An overview over recent Tevatron vector boson+jets measurements is given with an emphasis on comparisons between data and the predictions of…
This paper presents cross sections for the production of a W boson in association with jets, measured in proton--proton collisions at $\sqrt{s}=7$ TeV with the ATLAS experiment at the Large Hadron Collider. With an integrated luminosity of…
The CDF and D0 collaborations performed a comprehensive study of the production of vector bosons, W and Z, in association with energetic jets. Understanding the W/Z + jets and W/Z + c, b-jets processes is of paramount importance for the top…
The production of a Higgs boson in association with a pair of top-antitop or bottom-antibottom quarks plays a very important role at both the Tevatron and the Large Hadron Collider. The theoretical prediction of the corresponding cross…
We study the production of a charged Higgs boson in association with a W boson at the CERN Large Hadron Collider in the context of the minimal supersymmetric extension of the standard model. This production mechanism is particularly…
The start of the physics program at the LHC has added great impetus in the development of powerful theoretical tools to meet the many challenges that this collider brings. The production of jets and weak vector bosons is at the center of…
We present the complete calculation of $W$-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order in perturbative QCD. To cancel infrared divergences we introduce a new subtraction method…
