Events consistent with the production of a Higgs boson in association with a leptonically decaying Z boson are analysed. Long-lived particle (LLP) decays are reconstructed from inner-detector tracks as displaced vertices with high mass and track multiplicity relative to Standard Model processes. The analysis selection requires the presence of at least two displaced vertices, effectively suppressing Standard Model backgrounds. The residual background contribution is estimated using a data-driven technique. No excess over Standard Model predictions is observed, and upper limits are set on the branching ratio of the Higgs boson to LLPs. Branching ratios above 10% are excluded at 95% confidence level for LLP mean proper lifetimes cτ as small as 4 mm and as large as 100 mm. For LLP masses below 40 GeV, these results represent the most stringent constraint in this lifetime regime."],["dc.identifier.citation","Journal of High Energy Physics. 2021 Nov 30;2021(11):229"],["dc.identifier.doi","10.1007/JHEP11(2021)229"],["dc.identifier.pii","17269"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/97979"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112910"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-507"],["dc.publisher","Springer Berlin Heidelberg"],["dc.relation.eissn","1029-8479"],["dc.rights.holder","The Author(s)"],["dc.subject","Exotics"],["dc.subject","Hadron-Hadron scattering (experiments)"],["dc.subject","Higgs physics"],["dc.subject","proton-proton scattering"],["dc.subject","Lifetime"],["dc.title","Search for exotic decays of the Higgs boson into long-lived particles in pp collisions at $ \\sqrt{s} $ = 13 TeV using displaced vertices in the ATLAS inner detector"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]
