We show that the $(b\\bar{b})(b\\bar{b})$ final state in Higgs boson pair production can be exploited in the boosted regime to give constraints on the trilinear Higgs boson self-coupling. In these exclusive phase space regions, novel jet substructure techniques can be used to separate the signal from the large QCD and electroweak backgrounds. New developments on trigger and b-tagging strategies for the upcoming LHC runs are necessary in order to reconstruct the Higgs bosons in boosted final states, where the trilinear self-coupling sensitivity is reduced. We find that using our approach one can set a limit for $\\lambda \\leq 1.2$ at $95 \\%$ CL after $3000~\\mathrm{fb}^{-1}$. As the signal-to-background ratio is small we propose a data-driven side-band analysis to improve on the coupling measurement.", "revisions": [ { "version": "v2", "updated": "2014-08-13T15:28:34.000Z" } ], "analyses": { "keywords": [ "standard model higgs boson pair", "model higgs boson pair production", "final state", "novel jet substructure techniques", "trilinear higgs boson" ], "tags": [ "journal article" ], "publication": { "publisher": "Springer", "journal": "J.
