      abstract     = {A search is performed for a new resonance X decaying into
                      either a pair of Higgs bosons (HH) or into a Higgs boson and
                      a new scalar boson Y (HY), using proton-proton collision
                      data collected at $\sqrt{s}$ = 13 TeV, corresponding to an
                      integrated luminosity of 138 fb$^{-1}$. 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 pp
                      $\to$ HH production is 1 pb for a high-mass resonance. For
                      HY production, the upper limit on the cross section of the
                      process pp $\to$ X $\to$ 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
                      $γγ$ or $ττ$ and Y decays into a pair of bottom quarks
                      or massive vector bosons.},
