The observed distribution of the invariant mass of the three final-state particles, m(llgamma), is consistent with the Standard Model hypothesis in the investigated mass range of 120-150 GeV. For a Higgs boson with a mass of 125.5 GeV, the observed upper limit at the 95% confidence level is 11 times the Standard Model expectation. Upper limits are set on the cross section times branching ratio of a neutral Higgs boson with mass in the range 120-150 GeV between 0.13 and 0.5 pb for sqrt(s)=8 TeV at 95% confidence level.", "revisions": [ { "version": "v1", "updated": "2014-02-13T07:33:34.000Z" } ], "analyses": { "keywords": [ "pp collisions", "higgs boson decays", "atlas detector", "neutral higgs boson", "cross section times branching ratio" ], "tags": [ "journal article" ], "publication": { "doi": "10.1016/j.physletb.2014.03.015", "journal": "Physics Letters B", "year": 2014, "month": "May", "volume": 732, "pages": 8 }, "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1281233, "adsabs": "2014PhLB..732....8A" } } }
