Search for heavy resonances in the H tagged dijet mass spectrum in pp collisions at 8 TeV

Abstract: A search for heavy resonances decaying into a pair of 125 GeV Higgs bosons is performed in proton-proton collisions collected by the CMS experiment at the LHC at $\sqrt{s} = $ 8 TeV. The dataset corresponds to an integrated luminosity of 19.7 fb$^{-1}$. Only the decay of Higgs bosons into b quark pairs is considered. For resonance masses above 1 TeV, each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can be reconstructed as one massive jet. The signal is characterized as a peak in the dijet invariant mass distribution. The background from multijet events is suppressed by applying requirements on jet b quark content, mass, and substructure. No evidence for a signal is observed. An upper limit on the signal production cross section is derived as a function of the resonance mass. The results are interpreted as exclusion limits on radion excitations in models with warped extra dimensions.
