Résumé : A search for the standard model Higgs boson (H) decaying to bb̄ when produced in association with a weak vector boson (V) is reported for the following channels: W(MuNu)H, W(eNu)H, W(TauNu)H, Z(MuMu)H, Z(ee)H, and Z(NuNu)H. The search is performed in data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at sqrt(s)
