We systematically investigate the uncertainties in computing the production of W±, Z with large transverse momentum in pp̄ interactions. We argue that the rates for "anomalous" lepton-pT-jet event can be consistent with the standard model prediction for the process pp → W( → lv)+gluons. As a result we also predict enhanced "monojet" cross sections from pp → Z( → vv)+gluons, although the overall rate is still somewhat low. This discrepancy would be remedied if there exist more than three light neutrinos, as is predicted by some family-unifying theories.
