Search for the b¯b decay of the Standard Model Higgs boson in associated (W/Z)H production with the ATLAS detector

Abstract: A search for the (Formula presented.) decay of the Standard Model Higgs boson is performed with the ATLAS experiment using the full dataset recorded at the LHC in Run 1. The integrated luminosities used are 4.7 and 20.3 fb −1 from pp collisions at (Formula presented.) and 8 TeV, respective...
