Wand Z production in association with light and heavy-flavour jets at the LHC and the Tevatron

Abstract

Recent results on W and Z production in association with light and heavy-flavour jets at the Tevatron and the LHC are reviewed. The integrated luminosity which is used for physics analysis by each of the two Tevatron experiments (CDF and D0) corresponds to a maximum of ≈10 fb−1, at an energy in the centre of massof 1.96 TeV. The LHC analyses of ATLAS and CMS use the data sample collected in 2011 which corresponds to an integrated luminosity of ≈5 fb−1, at an energy in the centre of mass of 7 TeV. Events with W and Z bosons accompanied by jets represent one of the main background samples in the analyses of rare Standard Model processes and in searches for New Physics. Furthermore these measurements provide a test of perturbative QCD calculations and probe the strange and heavy flavour content of the proton.
