The properties of the Higgs boson measured in bosonic decay channels (HβΞ³Ξ³, HβZZββ4β, HβWWβββΞ½βΞ½, HβZΞ³) with
25 fbβ1 of pp collision data from the Large Hadron Collider run-1
collected by the ATLAS experiment are presented. The results include an
improved measurement of the mass of the Higgs boson from a combined fit to the
invariant mass spectra of the decay channels HβΞ³Ξ³ and
HβZZββ4β, which yields mHβ=125.36Β±0.37
(stat) Β±0.18 (syst) GeV = 125.36Β±0.41 GeV and supersedes the
previous result from ATLAS.Comment: 6 pages, 8 figures, Large Hadron Collider Physics (LHCP) Conference
