Abstract
A detailed analysis is given of processes involving the production of heavy vector bosons as sources of events with a single hadronic jet balanced by a large missing energy or possibly a charged largep T lepton and missing energy. In particular, the hadronic channels of the τ lepton produced inW ± decays provide an appreciable rate of monojet events, with energetic narrow jets of low charged multiplicity. Furthermore it is shown that higher order QCD corrections to weak boson production, in particular the Compton like processqg→Zq orqg→Wq are an appreciable source of the types of events mentioned above.

The diagrams involved are similar to those involved in the calculation of the corrections to the weak boson production at largep T . TheK-factor was rather larger (∼1.5) at\(\sqrt s = 540 GeV\)
