Findings

Method achieves uniform signal efficiency and background rejection.

LHC sensitivity to Higgs pair production is significantly improved.

Unified approach replaces multiple separate experimental searches.

Abstract

In this contribution, we study the resonant pair production of heavy particles in hadronic final states using jet substructure techniques. We discuss a recently proposed resonance tagging strategy, which interpolates between the highly boosted and fully resolved regimes, leading to uniform signal efficiencies and background rejection rates for a broad range of masses. With this method, one can efficiently replace independent experimental searches, based on different final state topologies, with a single common analysis. We show using this strategy that the LHC has sensitivity to the enhanced resonant production of Higgs boson pairs decaying into $b\bar{b}$ pairs in generic New Physics scenarios.
