The search uses 139 fb-1 of proton-proton collision data at a center-of-mass energy of √s = 13 TeV recorded between 2015 and 2018 by the ATLAS experiment at the LHC. A narrow dimuon resonance is searched for in the invariant mass spectrum between 16 GeV and 62 GeV. The largest excess of events above the Standard Model backgrounds is observed at a dimuon invariant mass of 52 GeV and corresponds to a local (global) significance of 3.3σ (1.7σ). Upper limits at 95% confidence level are placed on the branching ratio of the Higgs boson to the bbμμ final state, B(H → aa → bbμμ), and are in the range 0.2-4.0 × 10-4, depending on the signal mass hypothesisAmerican Physical SocietyDepartamento de Física TeóricaFacultad de Ciencias20222022-01-11research articlehttp://purl.org/coar/resource_type/c_2df8fbb1VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10486/706168https://dx.doi.org/10.1103/PhysRevD.105.012006reponame:Biblos-e Archivo.
