| Abstract | This note presents an updated search with the ATLAS experiment for the Standard Model Higgs boson produced in association with a WWW or ZZZ boson and decaying to bbarbb\bar{b}bbarb using 4.7 \ifb\ of LHC proton-proton data at \SevenTeV\ and 13.0 \ifb\ at \EightTeV. The search is performed using events containing zero, one or two electrons or muons targeting the three decay modes \vvbb, \lvbb and ZHtoell+ell−bbarbZH \to \ell^+\ell^- b\bar{b}ZHtoell+ell−bbarb. No significant excess is observed. For mH=125m_H = 125mH=125 GeV, the observed (expected) upper 95\% confidence level limit on the cross section times the branching ratio is found to be 1.8 (1.9) times the Standard Model prediction. A Standard Model Higgs boson with mH=110m_H = 110mH=110 GeV is excluded. As a validation of the analysis procedure, the production of diboson pairs, WZWZWZ and ZZZZZZ, with a ZZZ boson decaying to bbarbb\bar{b}bbarb, has been observed with a significance of 4.0 standard deviations and a rate compatible with the Standard Model expectation. |
