Abstract
Measuring the Higgs boson couplings as precisely as possible is one of the major goals of the High Luminosity LHC. We show that the ( bb ¯ )( bb ¯ ) 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 λ ≤ 1.2 at 95% CL after 3000 fb−1. As the signal-to-background ratio is small, we propose a data-driven side-band analysis to improve on the coupling measurement.
