This study performs a comprehensive exploitation of the bbZZ events, encompassing the following decay topologies. One H candidate is identified through its decay into a bottom quark-antiquark pair, while the other H or the Y candidate is selected through its decay into a pair of Z bosons. One Z boson is required to decay leptonically and the other, to decay into a pair of quarks or neutrinos. Events of interest are categorized based on the Lorentz boosts of the hadronically decaying H and Z bosons. Machine-learning-based discriminants, together with the reconstructed resonance mass, are employed across the different categories to separate signal from backgrounds, and their corresponding distributions are included in a simultaneous fit. No significant deviations from the standard model predictions are observed. Upper limits at the 95% confidence level are set on the HH and HY production cross sections. For resonant HH production, the upper limit on the cross section of $\\mathrm{pp}\\to \\mathrm{X}\\to \\mathrm{HH}$ production is 1 pb for a high-mass resonance. For HY production, the upper limit on the cross section of the process $\\mathrm{pp}\\to \\mathrm{X}\\to \\mathrm{HY} \\to \\mathrm{bbZZ}$ is approximately 5 fb for a high-mass resonance. This is comparable to the sensitivity achieved in other analyses, which focus on H decays to $\\gamma\\gamma$ or $\\tau\\tau$ and Y decays into a pair of bottom quarks or massive vector bosons.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.167417.v1/t1","@type":"Dataset","description":"Pre-fit distributions of $\\Delta R(\\ell,\\ell)$ in the SR qq0M, combining the electron and muon channel and using all three data-taking...","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.167417.v1/t2","@type":"Dataset","description":"Pre-fit distributions of HT in the SR qq0M, combining the electron and muon channel and using all three data-taking years....","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.167417.v1/t3","@type":"Dataset","description":"Pre-fit distributions of $\\Delta R(\\ell_1,b_1)$ in the SR qq0M, combining the electron and muon channel and using all three data-taking...","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.167417.v1/t4","@type":"Dataset","description":"Pre-fit distributions of $\\Delta R(\\ell_1,b_2)$ in the SR qq0M, combining the electron and muon channel and using all three data-taking...","name":"Figure 2d"},{"@id":"https://doi.org/10.17182/hepdata.167417.v1/t5","@type":"Dataset","description":"The BDT score $\\mathrm{S_{BDT}}$ distribution in the fully resolved SR qq0M.
