Search for Higgs boson decays into Z and J/$\psi$ and for Higgs and Z boson decays into J/$\psi$ or ${\rm Y}$ pairs in pp collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

Decays of the Higgs boson into a Z boson and a J/$\psi$ or $\psi$(2S) meson are searched for in four-lepton final states with the CMS detector at the LHC. A data set of proton-proton col…
