The analysed data set corresponds to an integrated luminosity of 137 fb$^{-1}$. Events are selected in which the Z boson decays into a pair of electrons or a pair of muons, and the $\\rho$ and $\\phi$ mesons decay into pairs of pions and kaons, respectively. No significant excess above the background model is observed. As different polarization states are possible for the decay products of the Z boson and $\\rho$ or $\\phi$ mesons, affecting the signal acceptance, scenarios in which the decays are longitudinally or transversely polarized are considered. Upper limits at the 95% confidence level on the Higgs boson branching fractions into Z$\\rho$ and Z$\\phi$ are determined to be 1.04-1.31% and 0.31-0.40%, respectively, where the ranges reflect the considered polarization scenarios; these values are 740-940 and 730-950 times larger than the respective standard model expectations. These results constitute the first experimental limits on the two decay channels.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95908.v1/t1","@type":"Dataset","description":"Observed and expected 95% CL upper limits on B(H $\\rightarrow$ Z$\\rho$), for different polarizations.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.95908.v1/t2","@type":"Dataset","description":"Observed and expected 95% CL upper limits on B(H $\\rightarrow$ Z$\\phi$), for different polarizations.","name":"Table 4"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1806506?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/95908"}],"inLanguage":"en","name":"Search for decays of the 125 GeV Higgs boson into a Z boson and a $\\rho$ or $\\phi$ meson","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1806506?version=1","version":1}
