10. Use of the jet mass in the reconstruction of hadronic W and Z boson decays in the D0 experiment

Use of the jet-mass variable can significantly improve the reach of searches for high-mass diboson resonances. Traditional searches for this process have focused on the purely leptonic final state to reduce contamination from the large QCD jet background. We show that the significance to diboson resonances can be enhanced when considering events with one or two leptons and at least one...

30. W/Z + jets with the CMS detector

We present a study of jet production in association with W and Z bosons in proton-proton collisions at ECM=7 TeV using the full 2010 data set collected by CMS corresponding to an integrated luminosity of 36+-4 pb-1. The production of vector bosons with jets provides a stringent and important test of perturbative QCD calculations, and is an important background in searches for new physics and...

11. Methods and algorythms in CDF for diboson production in hadronic final states

Alexandru Rusu (Fermilab)

A benchmark for Higgs discovery at the Tevatron is the diboson production in hadronic final states. Before every finding of the Higgs we have to show that we can re-discover this known Standard Model process. The same set of techniques used for Higgs can be tried on dibosons to see their effectiveness: jet reconstruction algorythms, b tagging methods, background reduction methods etc. I will...

31. Search for diboson production in the lepton + MET + bb channel in b-jet in final states

Marco Trovato (INFN, Pisa)

Studying diboson associated production in a final state with a lepton, neutrino, and bb-pair is important since the event topology of this process is the same as expected for associated production of a W and a Standard Model light-Higgs boson. Thus, we consider the search for Diboson production as a preliminary step towards the Higgs discovery. Here we present a search for WW/WZ in events with...

32. Vector boson productions and Higgs search in CMS

Jonatan Piedra (IFCA)

A review of CMS Higgs Boson searches with discovery and exclusion prospects for the coming LHC data is given. Measurements of related electroweak (di-)boson productions are also presented.
