Search for resonant pair production of Higgs bosons decaying to bottom quark-antiquark pairs in proton-proton collisions at 13 TeV

A search for a narrow-width resonance decaying into two Higgs bosons, each having a mass of $125~\mathrm{GeV}$ and decaying into a $\mathrm{b\bar{b}}$ pair, is presented. The search is performed using proton-proton collision data corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ at $\sqrt{s}=13~\mathrm{TeV}$ recorded by the CMS detector at the LHC. No evidence for a signal is observed and upper limits at a $95\%$ confidence level on the production cross section times branching fraction for such a resonance decaying to two Higgs bosons and each of them to $\mathrm{b\bar{b}}$ are set in the mass range from $260$ to $1200~\mathrm{GeV}$.
