  n this letter we investigate the various processes that can contribute to a
final state consisting of a lepton, missing transverse momentum and two jets at
Next to Leading Order (NLO) at the Tevatron. In particular we consider the
production of W/Z + 2 jets, diboson pairs, single top and the tt process with
both fully leptonic and semi-leptonic decays. We present distributions for the
invariant mass of the dijet system and normalisations of the various processes,
accurate to NLO.
