Higgs-pair production and decay in simplest little Higgs model [PDF]
Nuclear Physics B, 2010 In the framework of the simplest little Higgs model (SLHM), we study the production of a pair of neutral CP-even Higgs bosons at the LHC. First, we examine the production rate and find that it can be significantly larger than the SM prediction. Then we investigate the decays of the Higgs-pair and find that for a low Higgs mass their dominant decay mode

Probing the symmetric Higgs portal with di-Higgs boson production [PDF]
Physical Review D, 2019 A coupling of a scalar, charged under an unbroken global U(1) symmetry, to the Standard Model via the Higgs portal is one of the simplest gateways to a dark sector. Yet, for masses $m_{S}\geq m_{H}/2$ there are few probes of such an interaction. In this note we evaluate the sensitivity to the Higgs portal coupling of di-Higgs boson production at the ...

Two paths towards precision at a very high energy lepton collider
Journal of High Energy Physics, 2021 We illustrate the potential of a very high energy lepton collider (from 10 to 30 TeV center of mass energy) to explore new physics indirectly in the vector boson fusion double Higgs production process and in direct diboson production at high energy ...

Resolving the degeneracy in single Higgs production with Higgs pair production
Physics Letters B, 2016 The Higgs boson production can be affected by several anomalous couplings, e.g. $c_t$ and $c_g$ anomalous couplings. Precise measurement of $gg\to h$ production yields two degenerate parameter spaces of $c_t$ and $c_g$; one parameter space exhibits the SM limit while the other does not. Such a degeneracy could be resolved by Higgs boson pair production.

Higgs Boson production in [PDF]
Physics Letters B, 1995 Abstract The production of the Standard Model Higgs boson in the four-fermion reaction e + e − → μ + μsu−b b is studied. The complete tree-level matrix element, including signal and backgrounds in the standard electroweak theory, is computed and initial state radiation is taken into account in the leading-log approximation ...

Enhanced di-Higgs production in the two Higgs doublet model [PDF]
Journal of High Energy Physics, 2019 Abstract We show that the rate for di-Higgs production at the LHC can be enhanced by a factor as large as 25 compared to the Standard Model value in the two Higgs doublet model, while being consistent with the known properties of the observed Higgs boson h.

Sources of Charged Higgs Pair through Double or Triple Higgs Production at Linear Colliders
Advances in High Energy Physics, 2017 The production of triple Higgs (H+H-H0), (H+H-h0) and pairwise charged Higgs boson (H+H-) is studied in the context of future linear colliders within the two-Higgs-doublet model (2HDM) type II.

Probing Higgs couplings to light quarks via Higgs pair production
Journal of High Energy Physics, 2019 We consider the potential of the Higgs boson pair production process to probe the light quark Yukawa couplings. We show within an effective theory description that the prospects of constraining enhanced first generation light quark Yukawa couplings in ...

Two-loop infrared singularities in the production of a Higgs boson associated with a top-quark pair
Journal of High Energy Physics, 2022 The associated production of a Higgs boson and a top-quark pair is important for probing the Yukawa coupling of the top quark, and calls for better theoretical modeling.
