Higgs boson pair production in new physics models at hadron, lepton, and photon colliders

Research output: Contribution to journalArticlepeer-review

Abstract

We discuss Higgs boson pair production processes at future hadron and lepton colliders including the photon collision option in several new physics models, i.e. the two-Higgs-doublet model, the scalar leptoquark model, the sequential fourth-generation fermion model and the vectorlike quark model. Cross sections for these processes can differ significantly from the standard model predictions, due to the nondecoupling effect in the triple Higgs boson coupling constant. For the one-loop induced processes such as gg → hh and γγ → hh, new physics particles can mediate in a loop diagram, which can affect cross sections. Measurements of the Higgs boson pair production processes can be useful not only to test the standard model but also to explore new physics models.
