dc.description.abstractA search for decays of the Higgs and Zboson to pairs of J/?or Y(nS)(n =1, 2, 3) mesons, with their subsequent decay to ?+??pairs, is presented. The analysis uses data from proton-proton collisions at ?s=13 TeV, collected with the CMS detector at the LHC in 2017 and corresponding to an integrated luminosity of 37.5fb?1. 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/?pair channel, the limits are 1.8 ×10?3and 2.2 ×10?6for the Higgs and Zboson, respectively, while in the combined Y(nS)pair channel, the limits are 1.4 ×10?3and 1.5 ×10?6, respectively, when the mesons from the Higgs and Zboson decay are assumed to be unpolarized. When fully longitudinal and transverse polarizations are considered the limits reduce by about 22–29% and increase by about 10–13%, respectively.en_US
