Search for Associated Production of W and Higgs Bosons in lnu bb Final States

We present a search for the Higgs boson through its associated production with W for masses between 105 and 155 GeV in ppbar collisions at $\sqrt{s} =$~1.96 TeV. The search is performed in events containing one lepton (electron or muon), an imbalance in the transverse energy, and two b-tagged jets in 2 fb$^{-1}$ of integrated luminosity accumulated by the D0 experiment at Fermilab.
