Higgs properties with H->ZZ->4l in ATLAS

The ATLAS latest results on the properties of the Higgs boson in the \mbox{H $\rightarrow$ ZZ$^{(*)}$ $\rightarrow$ 4$\ell$} decay channel, using the complete LHC \mbox{Run-1} dataset, are presented. The mass of the particle is measured to be \mbox{m$_H$ = 124.3$^{+0.6}_{-0.5}$ (stat)$^{+0.5}_{-0.3}...

description The ATLAS latest results on the properties of the Higgs boson in the \mbox{H $\rightarrow$ ZZ$^{(*)}$ $\rightarrow$ 4$\ell$} decay channel, using the complete LHC \mbox{Run-1} dataset, are presented. The mass of the particle is measured to be \mbox{m$_H$ = 124.3$^{+0.6}_{-0.5}$ (stat)$^{+0.5}_{-0.3}$(syst) GeV}, with the the ratio of the observed cross section to the expected standard model cross section measured as $\mu$ = 1.7$^{+0.5}_{-0.4}$ at this mass. The categorisation of selected candidate events according to criteria based on Higgs boson production mechanisms allows the study of the coupling properties of the new particle. Additionally, the spin-parity of the particle is probed. A brief review of the analysis techniques and results is given here, with emphasis given to the studies of the coupling properties and spin-parity of the boson.
