dc.description.abstractThe final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H - GT ZZ* - GT l(+)l(-)l(+)l(-), where l, l = e or mu, are presented. These measurements were performed using pp collision data corresponding to integrated luminosities of 4.5 and 20.3 fb(-1) at center-of-mass energies of 7 and 8 TeV, respectively, recorded with the ATLAS detector at the LHC. The H - GT ZZ* - GT 4l signal is observed with a significance of 8.1 standard deviations, with an expectation of 6.2 standard deviations, at m(H) = 125.36 GeV, the combined ATLAS measurement of the Higgs boson mass from the H - GT gamma gamma and H - GT ZZ* - GT 4l channels. The production rate relative to the Standard Model expectation, the signal strength, is measured in four different production categories in the H - GT ZZ* - GT 4l channel. The measured signal strength, at this mass, and with all categories combined, is 1.44(-0.33)(+0.40). The signal strength for Higgs boson production in gluon fusion or in association with (tt) over bar or (bb) over bar pairs is found to be 1.7(-0.4)(+0.5), while the signal strength for vector-boson fusion combined with WH/ZH associated production is found to be 0.3(-0.9)(+1.6).en
