  Single-jet production with missing transverse momentum is one of the most
promising discovery channels for new physics at the LHC. In the Standard Model,
Z + jet production with a Z-boson decay into neutrinos leads to this monojet
signature. To improve the corresponding Standard Model predictions, we present
the calculation of the full next-to-leading-order (NLO) electroweak corrections
and a recalculation of the NLO QCD corrections to monojet production at the
Tevatron and the LHC. We discuss the phenomenological impact on the total cross
sections as well as on relevant differential distributions.
