Pair production of 125 GeV Higgs boson in the SM extension with color-octet scalars at the LHC [PDF]
, 2014 Although the Higgs boson mass and single production rate have been determined more or less precisely, its other properties may deviate significantly from its predictions in the standard model (SM) due to the uncertainty of Higgs data.

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 ...

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 ...

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 ...

Higgs boson interactions in supersymmetric theories with large tan beta [PDF]
, 1998 We show that radiative corrections to the Higgs potential in supersymmetric theories with large tan beta generically lead to large differences in the light Higgs boson decay branching fractions compared to those of the standard model Higgs boson.

A comparative study of Higgs boson production from vector-boson fusion
Journal of High Energy Physics, 2021 The data taken in Run II at the Large Hadron Collider have started to probe Higgs boson production at high transverse momentum. Future data will provide a large sample of events with boosted Higgs boson topologies, allowing for a detailed understanding ...
