The analysis is based on proton-proton collisions collected at $\\sqrt{s}=13\\,\\text{TeV}$ by the CMS experiment at the LHC, corresponding to an integrated luminosity of $138~\\mathrm{fb}^{-1}$. The nonresonant analysis targets the standard model ZZ and ZH processes in the $bb\\tau\\tau$ final state, motivated by the prominent role of this channel in searches for nonresonant Higgs boson pair production. The resonant searches target physics beyond the standard model, probing heavy spin-0 resonances X that decay into ZZ and spin-1 resonances Z' that decay into ZH, with masses in the 0.2-5 and 0.5-6 TeV ranges, respectively. Upper limits at 95% confidence level are set on the product of production rate and branching fraction $\\sigma(\\mathrm{X})\\mathcal{B}(\\mathrm{X}\\to\\mathrm{ZZ})$, ranging from $300~\\mathrm{pb}$ to $24~\\mathrm{fb}$, and $\\sigma(\\mathrm{Z}')\\mathcal{B}(\\mathrm{Z}'\\!\\to\\!\\mathrm{ZH})$, ranging from $0.4~\\mathrm{pb}$ to $12~\\mathrm{fb}$. These are the first measurements to probe the $\\mathrm{ZZ}/\\mathrm{ZH}\\to{}\\mathrm{bb}\\tau\\tau$ processes. No deviation from standard model expectations is observed.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.169547.v1/t1","@type":"Dataset","description":"Distributions of the output of the DNN used for SM $ZZ\\to{}bb\\tau\\tau$ signal extraction.
