Multi-Higgs production provides a phenomenologically clear window to the electroweak symmetry-breaking sector. We perform a comprehensive and comparative analysis of new electroweak physics effects in di-Higgs and di−Higgs+jet production. In particular, we discuss resonant di-Higgs phenomenology, which arises in the Higgs portal model and in the minimal supersymmetric Standard Model at small tanβ, and nonresonant new-physics contributions to di-Higgs production in models where the newly discovered Higgs candidate is interpreted as a pseudo-Nambu-Goldstone boson. We show that, for all these scenarios, a measurement of the di-Higgs and di−Higgs+jet final states provides an accessible and elaborate handle to understand electroweak symmetry breaking in great detail.
