The analysis uses data from proton-proton collisions with an integrated luminosity of 35.9 fb$^{-1}$ at $\\sqrt{s}$ = 13 TeV collected with the CMS detector at the LHC. The observed limit on the $Z\\rightarrow J/\\psi\\gamma$ decay branching fraction, assuming that the J/$\\psi$ meson is produced unpolarized, is $1.4\\times10^{-6}$ at 95% confidence level, which corresponds to a rate higher than expected in the standard model by a factor of 15. For extreme-polarization scenarios, the observed limit changes from -13.6 to +8.6% with respect to the unpolarized scenario. The observed upper limit on the branching fraction for $H\\rightarrow J/\\psi\\gamma$ where the J/$\\psi$ meson is assumed to be transversely polarized is $7.6\\times 10^{-4}$, a factor of 260 larger than the standard model prediction. The results for the Higgs boson are combined with previous data from proton-proton collisions at $\\sqrt{s}$ = 8 TeV to produce an observed upper limit on the branching fraction for $H\\rightarrow J/\\psi\\gamma$ that is a factor of 220 larger than the standard model value.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.89175.v1/t1","@type":"Dataset","description":"Upper observed and expected limits on branching fraction of $Z (H)\\rightarrow J/\\psi\\gamma$ decay of the $Z (H)$ boson.","name":"Table 3"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1700175?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/89175"}],"inLanguage":"en","name":"Search for rare decays of Z and Higgs bosons to J$/\\psi$ and a photon 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/ins1700175?version=1","version":1}
