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

Mostrar todas las versiones(2)

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...

The analysis procedure is validated by a measurement of the yield of (W/Z)Z production with (Formula presented.) in the same final states as for the Higgs boson search, from which the ratio of the observed signal yield to the Standard Model expectation is found to be 0.74 ± 0.09 (stat.) ± 0.14 (syst.).[Figure not available: see fulltext.]. © 2015, The Author(s).
