A search for the standard model Higgs boson (H) decaying to bb when produced in association with weak vector bosons (V) is reported for the following modes: W(lν)H, Z(ll)H and Z(νν)H. The search is performed in a data sample corresponding to an integrated luminosity of 4.7 /fb and 12/13 /fb, recorded by the CMS and ATLAS detectors in proton-proton collisions at the LHC with a center-of-mass energy of 7 TeV and 8 TeV.
