The analysis uses data from proton-proton collisions at $\\sqrt{s} = 13$ TeV, collected with the CMS detector at the LHC in 2017 and corresponding to an integrated luminosity of 37.5 fb$^{\u22121}$ . While an observation of such a decay with this sample would indicate the presence of physics beyond the standard model, no significant excess is observed. Upper limits at 95% confidence level are placed on the branching fractions of these decays. In the $J/\\psi$ pair channel, the limits are $1.8 \\times 10^{-3}$ and $2.2 \\times 10^{-6}$ for the Higgs and Z boson, respectively, while in the combined $\\Upsilon(nS)$ pair channel, the limits are $1.8 \\times 10^{-3}$ and $1.5 \\times 10^{-6}$ , respectively, when the mesons from the Higgs and Z boson decay are assumed to be unpolarized. When fully longitudinal and transverse polarizations are considered the limits reduce by about $22\u201329$% and increase by about $10\u201313$%, respectively.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.90709.v1/t1","@type":"Dataset","description":"Exclusion limits at 95% CL for the branching fractions ($\\mathcal{B}$s) of the $H$ and $Z$ boson decays to $J/\\psi$ or...","name":"Table 1"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1736895?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/90709"}],"inLanguage":"en","name":"Search for Higgs and Z boson decays to J/$\\psi$ or $\\Upsilon$ pairs in proton-proton collisions at $\\sqrt{s}=$ 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1736895?version=1","version":1}
