Probing Higgs couplings to light quarks via Higgs pair production

open access: yesJournal 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 ...

A comparative study of Higgs boson production from vector-boson fusion

open access: yesJournal 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 ...

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)

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 ...

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.

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

Physics case for an e+e− collider at 500 GeV and above [PDF]

open access: yesEPJ Web of Conferences
Some highlights of the physics case for running an e+e− collider at 500 GeV and above are discussed with a particular emphasis on the experimental access to the Higgs potential via di-Higgs and (at sufficiently high energy) triple Higgs production.
