Di-Higgs resonance searches in weak boson fusion

Understand

The search for di-Higgs final states is typically limited at the LHC to the dominant gluon fusion channels, with weak boson fusion only assuming a spectator role.

• In this work, we demonstrate that when it comes to searches for resonant structures that arise from iso-singlet mixing in the Higgs sector, the weak boson fusion sideline can indeed contribute to winning the discovery game.
• Extending existing experimental resonance searches by including both contributions is therefore crucial.
