Measurements of Higgs boson production and couplings in the four-lepton channel in pp collisions at center-of-mass energies of 7 and 8 TeV with the ATLAS detector
The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H → ZZ → lþl−l0þl0−, where l, l0 ¼ e or μ, 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...

| 520 | 3 | |a The final ATLAS Run 1 measurements of Higgs boson production and couplings in the decay channel H → ZZ → lþl−l0þl0−, where l, l0 ¼ e or μ, 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 → ZZ → 4l signal is observed with a significance of 8.1 standard deviations, with an expectation of 6.2 standard deviations, at mH ¼ 125.36 GeV, the combined ATLAS measurement of the Higgs boson mass from the H → γγ and H → ZZ → 4l channels. The production rate relative to the Standard Model expectation, the signal strength, is measured in four different production categories in the H → ZZ → 4l channel. The measured signal strength, at this mass, and with all categories combined, is 1.44þ0.40 −0.33 . The signal strength for Higgs boson production in gluon fusion or in association with t¯t or b¯b pairs is found to be 1.7þ0.5 −0.4 , while the signal strength for vector-boson fusion combined with WH=ZH associated production is found to be 0.3þ1.6 −0.9 . | |
