Associated Production of a W Boson and One b Jet
نویسندگان
چکیده
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 to include them all in order to have a complete description at both colliders.

The existence of a new massive charged gauge boson, known as W’, is proposed by many new physics scenarios. When W’ decays to tb, the final state is very similar to the final state of the s-channel single top production, where W boson is the off-shell mediator to produce the top and bottom quarks. If W’ exists, it can affect the cross section of the SM s-channel single top production, so measur...
متن کاملMeasurement of the cross section for the production of a W boson in association with b-jets in pp collisions at √s=7 TeV with the ATLAS detector
Article history: Received 7 September 2011 Received in revised form 19 December 2011 Accepted 19 December 2011 Available online 22 December 2011 Editor: H. Weerts A measurement is presented of the cross section for the production of a W boson with one or two jets, of which at least one must be a b-jet, in pp collisions at √ s = 7 TeV. Production via top decay is not included in the signal defin...
متن کاملStudy of W boson production in association with beauty and charm
The associated production of a W boson with a jet originating from either a light parton or heavy-flavor quark is studied in the forward region using proton-proton collisions. The analysis uses data corresponding to integrated luminosities of 1.0 and 2.0 fb−1 collected with the LHCb detector at center-of-mass energies of 7 and 8 TeV, respectively. The W bosons are reconstructed using the W → μν...
متن کاملStudies of forward jets and production of W, Z bosons at LHC energies
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 dy-namical features of the matrix elements controlling the resummation of logarithmically enhanced corrections in √ s/E T , where E T is the jet production transverse energy. In case of production of W, Z boson...
متن کاملPossibilities of tt̄H Event Reconstruction
A light Standard Model Higgs boson can be produced in association with tt̄ in the process pp → tt̄H and detected in the final state bb̄bb̄qq̄lν. The cross section of this channel is not large, but there are only few sources of Standard Model background with similar event structures. Here we investigate how the correct b jets can be selected in view of H mass reconstruction. We discuss three methods ...
