Abstract: A search is presented for a heavy resonance decaying into a Z boson and a Higgs (H) boson. The analysis uses data from proton-proton collisions at a centre-of-mass energy of 13 TeV corresponding to 138 fb $^{-1}$ of integrated luminosity, recorded with the CMS experiment in the years 2016 to 2018. Resonance masses between 1.4 and 5 TeV are considered, resulting in large transverse momenta of the Z and H bosons. The search targets the Z boson decay into two electrons, two muons, or two neutrinos. The H boson is reconstructed with a single large-radius jet, recoiling against the Z boson. The search is designed for the hadronic H boson decay modes $\mathrm{H} \to \mathrm{c}\bar{\mathrm{c}}$ and $\mathrm{H} \to \mathrm{V}\mathrm{V}^{*} \to$ 4 quarks, where V denotes a W or Z boson. It achieves complementary sensitivity to previous searches targeting the $\mathrm{H}\to \mathrm{b}\bar{\mathrm{b}}$ decays for high resonance masses.
