Description
The production of W and Z bosons in association with multiple
jets at hadron colliders probes important aspects of QCD dynamics, and
forms an important class of backgrounds to new physics searches. With the
increase in energy from the Tevatron to the LHC, new kinematic regions
open up, in which weak bosons can be energetically subdominant to the
jets. Because the LHC is a pp machine, W bosons are produced primarily
left-handed, even at large transverse momentum, which strongly impacts
their decays to leptons. Recently the production rates for W bosons with
up to four additional jets, and Z bosons with up to three jets, have been
computed at next-to-leading-order in QCD, allowing more precise
theoretical predictions of these processes to confront the initial LHC
data.
