Sources of Charged Higgs Pair through Double or Triple Higgs Production at Linear Colliders

open access: yesAdvances 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.

Constraining the Higgs self-couplings at e+e− colliders

open access: yesJournal of High Energy Physics, 2018
We study the sensitivity to the shape of the Higgs potential of single, double, and triple Higgs production at future e + e − colliders. Physics beyond the Standard Model is parameterised through the inclusion of higher-dimensional operators (Φ†Φ−v 2 /2)

Sensitivity to triple Higgs couplings via di-Higgs production in the 2HDM at $$e^+e^-$$ e + e - colliders

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
An important task at future colliders is the investigation of the Higgs-boson sector. Here the measurement of the triple Higgs coupling(s) plays a special role.

Higgs probes of top quark contact interactions and their interplay with the Higgs self-coupling

open access: yesJournal of High Energy Physics, 2022
We calculate the dominant contributions of third generation four-quark operators to single-Higgs production and decay. They enter via loop corrections to Higgs decays into gluons, photons and b b ¯ $$ b\overline{b} $$ , and in Higgs production via gluon ...

Pair Production of Beyond the Standard Model Higgs Bosons

open access: yesEPJ Web of Conferences, 2017
Higgs pair production is not only sensitive to the trilinear Higgs self-coupling, but it can give access to other anomolous couplings, as e.g. a novel hhtt̄ coupling. In Composite Higgs Models, this coupling usually leads to a large increase of the cross

Production of Very Massive Higgs Bosons

open access: yesPhysics Letters B, 1984
Abstract We compare Higgs boson production mechanisms at multi-TeV hadronic colliders. In addition to the previously investigated processes gluon + gluon → H and q q → V ∗ → VH ( V = W, Z ) , we consider Higgs boson formation by pairs of virtual W's or Z's, a process analogous to two-photon collisions in e+e− scattering.

Enhanced di-Higgs production in the two Higgs doublet model [PDF]

open access: yesJournal 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.

Higgs Boson Studies at the Tevatron [PDF]

open access: yes, 2013
We combine searches by the CDF and D0 Collaborations for the standard model Higgs boson with mass in the range 90--200 GeV$/c^2$ produced in the gluon-gluon fusion, $WH$, $ZH$, $t{\bar{t}}H$, and vector boson fusion processes, and decaying in the $H ...

Probing the symmetric Higgs portal with di-Higgs boson production [PDF]

open access: yesPhysical 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 ...
