The associated Z vector boson production rate of the Standard Model Higgs boson

has been measured in decays into two b quarks, with the Z boson decaying into an

electron or muon pair in the ATLAS detector at the Large Hadron Collider (LHC).

The associated Z vector boson production cross section in the Standard Model is

almost two orders of magnitude smaller than the dominant Higgs boson production

cross section from gluon fusion. Proton-proton collision data at a centre-of-mass

energy of 8 TeV delivered by the LHC with the ATLAS detector corresponding to

an integrated luminosity of 13 fb−1 has been analysed. A Higgs boson produced via

associated production with a Z vector boson is excluded with a 95% confidence level

in a mass range between 110 to 130 GeV at 6 to 11 times the Standard Model cross section, respectively.
