A search has been performed for heavy resonances decaying to ZZ or ZW and foraxion-like particles (ALPs) mediating nonresonant ZZ or ZH production, in finalstates with two charged leptons ($\ell$ = e, $\mu$) produced by the decay of aZ boson, and two quarks produced by the decay of a Z, W, or Higgs boson H. Theanalysis is sensitive to resonances with masses in the range 450 to 2000 GeV.Two categories are defined corresponding to the merged or resolvedreconstruction of the hadronically decaying boson. The search is based on datacollected during 2016-2018 by the CMS experiment at the LHC in proton-protoncollisions at a center-of-mass energy of 13 TeV, corresponding to an integratedluminosity of 138 fb$^{-1}$. No significant excess is observed in the dataabove the standard model background expectation. Upper limits on the productioncross section of heavy, narrow spin-2 and spin-1 resonances are derived asfunctions of the resonance mass, and exclusion limits on the production of bulkgraviton particles and W$'$ bosons are calculated in the framework of thewarped extra dimensions and heavy vector triplet models, respectively. Inaddition, upper limits on the ALP-mediated diboson production cross section andALP couplings to standard model particles are obtained in the framework oflinear and chiral effective field theories. These are the first limits onnonresonant ALP-mediated ZZ and ZH production obtained by the LHC experiments.
