Abstract: A search is conducted for a beyond-the-Standard-Model boson using events where a Higgs boson with mass 125 GeV decays to four leptons (? = e or ?). This decay is presumed to occur via an intermediate state which contains one or two on-shell, promptly decaying bosons: H ? ZX/XX ? 4?, where X is a new vector boson Zd or pseudoscalar a with mass between 1 and 60 GeV. The search uses pp collision data collected with the ATLAS detector at the LHC with an integrated luminosity of 36.1 fb?1 at a centre-of-mass energy s=13 TeV. No significant excess of events above Standard Model background predictions is observed; therefore, upper limits at 95% confidence level are set on modelindependent fiducial cross-sections, and on the Higgs boson decay branching ratios to vector and pseudoscalar bosons in two benchmark models.[Figure not available: see fulltext.]. © 2018, The Author(s).
