A search for heavy resonances decaying to a pair of Standard Model Higgs bosons (H) is performed using data from proton-proton collisions at a centre-of-mass energy of 13 TeV, collected by the CMS experiment in 2015, corresponding to an integrated luminosity of 2.7 inverse femtobarns. The final state under consideration consists of both Higgs bosons decaying to b quark-antiquark pairs. For resonance masses above 1 TeV the Higgs bosons are highly Lorentz-boosted and thus each Higgs to b quarks pair is usually reconstructed as one hadronic jet. The signal is characterized as a peak in the distribution of the invariant mass of such dijet candidates. The signal strength for different assumed resonance masses will be estimated by a combined likelihood fit of background and signal shapes to the data. The search is performed in the context of search for s-channel production of new particles, namely Bulk Gravitons and Scalar Radions, testing the theoretical model of the Warped Extradimensional extension of the Standard Model.
