Search for a massive resonance decaying to a pair of Higgs bosons in the four b quark final state in proton–proton collisions at s=13TeV
A search for a massive resonance decaying into a pair of standard model Higgs bosons, in a final state consisting of two b quark–antiquark pairs, is performed. A data sample of proton–proton collisions at a centre-of-mass energy of 13 TeV is used, collected by the CMS experiment at the CERN LHC in...

| Summary: | A search for a massive resonance decaying into a pair of standard model Higgs bosons, in a final state
consisting of two b quark–antiquark pairs, is performed. A data sample of proton–proton collisions
at a centre-of-mass energy of 13 TeV is used, collected by the CMS experiment at the CERN LHC in
2016, and corresponding to an integrated luminosity of 35.9 fb−1. The Higgs bosons are highly Lorentzboosted
and are each reconstructed as a single large-area jet. The signal is characterized by a peak in
the dijet invariant mass distribution, above a background from the standard model multijet production.
The observations are consistent with the background expectations, and are interpreted as upper limits on
the products of the s-channel production cross sections and branching fractions of narrow bulk gravitons
and radions in warped extra-dimensional models. The limits range from 126 to 1.4 fb at 95% confidence
level for resonances with masses between 750 and 3000 GeV, and are the most stringent to date, over
the explored mass range. |
