A new search for Higgs boson pairs with the CMS experiment has pushed us closer than ever to a measurement of the Higgs boson self-coupling.

Discovering new physics beyond the Standard Model is a major objective of the experiments at the Large Hadron Collider. Signatures of beyond-the-Standard-Model physics that contain particles with long lifetimes have been largely unexplored so far, due to the complexity of their reconstruction. Thanks to the maturity reached by the LHC experiments, the community now turns its attention to these challenging searches. Long-lived particles are the territory that the new CMS timing detector in development will help conquer.
