      abstract     = {A search is presented for massive narrow-width resonances
                      in the mass range of 1$-$4.5 TeV, decaying into pairs of
                      Higgs bosons (HH). The search uses proton-proton collision
                      data at a center-of-mass energy of 13 TeV collected with the
                      CMS detector at the CERN LHC during 2016$-$2018,
                      corresponding to an integrated luminosity of 138 fb$^{-1}$.
                      The analysis targets final states where one Higgs boson
                      decays into a pair of bottom quarks and the other into a
                      pair of tau leptons, X $\to$ HH
                      $\to$$\mathrm{b\bar{b}}τ^+τ^-$. It uses a single large jet
                      to reconstruct the H $\to$$\mathrm{b\bar{b}}$ decay, while
                      the H $\to$$τ^+τ^-$ decay products can either be contained
                      within a single large jet or appear as two isolated tau
                      leptons. The observed data are consistent with standard
                      model background expectations. Upper limits at 95\%
                      confidence level are set on the production cross section for
                      resonant HH production for masses between 1 and 4.5 TeV.
                      This analysis sets the most sensitive limits to date on X
                      $\to$ HH $\to$ $\mathrm{b\bar{b}}τ^+τ^-$ decays in the
                      mass range of 1.4 to 4.5 TeV.},
