AbstractAn important task at future colliders is the measurement of the triple Higgs coupling. Depending on its size relative to the Standard Model (SM) value, certain collider options result in a higher experimental accuracy. Within the framework of Two Higgs Doublet Models (2HDM) types I and II we investigate the allowed ranges for all triple Higgs couplings involving at least one light, SM-like Higgs boson. We take into account theoretical constraints (unitarity, stability), experimental constraints from direct Higgs-boson searches, measurements of the SM-like Higgs-boson properties, flavor observables and electroweak precision data. We find that the SM-type triple Higgs coupling w.r.t. its SM value, $$\lambda _{hhh}/\lambda _{\mathrm {SM}}$$ λ hhh / λ SM , can range between $$\sim -0.5$$ ∼ - 0.5 and $$\sim 1.5$$ ∼ 1.5 . Depending on which value is realized, the HL-LHC can compete with, or is clearly inferior to the ILC. We find the coupling $$\lambda _{hhH}$$ λ hhH between $$\sim -1.5$$ ∼ - 1.5 and $$\sim 1.5$$ ∼ 1.5 . Triple Higgs couplings involving two heavy Higgs bosons, $$\lambda _{hHH}$$ λ hHH , $$\lambda _{hAA}$$ λ hAA and $$\lambda _{hH^+H^-}$$ λ h H + H - can reach values up to $${{\mathcal {O}}}(10)$$ O ( 10 ) , roughly independent of the 2HDM type. This can lead to potentially strongly enhanced production of two Higgs-bosons at the HL-LHC or high-energy $$e^+e^-$$ e + e - colliders.
