Search for resonant Higgs boson pair production in four b quark final state using large-area jets in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$

A search is presented for pair production of the standard model Higgs boson using data from proton-proton collisions at a centre-of-mass energy of 13$~\mathrm{TeV}$, collected by the CMS experiment at the CERN LHC in 2016$-$2018, corresponding to an integrated luminosity of 138$~\mathrm{fb}^{-1}$. The final state consists of two b quark-antiquark pairs. The search is conducted in the region of phase space where at least one of the pairs is highly Lorentz-boosted and is reconstructed as a single large-area jet. The other pair may be either similarly boosted or resolved, the latter reconstructed using two b-tagged jets. The data was found to be consistent with the measured standard model processes. Limits in the range 9.74$-$0.29$~$fb and 4.94$-$0.19$~$fb were set on the product of the cross sections and the branching fractions of the spin-0 radion and the spin-2 bulk graviton with a mass of 1$-$3$~\mathrm{TeV}$, respectively, in the context of warped extradimensional models.
