Anomalous couplings in double Higgs production [PDF]

open access: yesJournal of High Energy Physics, 2012
The process of gluon-initiated double Higgs production is sensitive to non-linear interactions of the Higgs boson. In the context of the Standard Model, studies of this process focused on the extraction of the Higgs trilinear coupling.

Constraints on anomalous Higgs boson couplings from its production and decay using the WW channel in proton–proton collisions at $$\sqrt{s} = 13~\text {TeV}$$ s = 13 TeV [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields
A study of the anomalous couplings of the Higgs boson to vector bosons, including $${\textit{CP}}$$ CP -violation effects, has been conducted using its production and decay in the WW channel.

Resolving the degeneracy in single Higgs production with Higgs pair production

open access: yesPhysics Letters B, 2016
The Higgs boson production can be affected by several anomalous couplings, e.g. ct and cg anomalous couplings. Precise measurement of gg→h production yields two degenerate parameter spaces of ct and cg; one parameter space exhibits the SM limit while the

Anomalous Higgs boson couplings in vector boson fusion at the CERN LHC [PDF]

open access: yesPhysical Review D, 2006
Deviations from SM expectations in the Higgs sector can be parameterized by an effective Lagrangian. The corresponding anomalous couplings have been implemented in a Monte Carlo program for Higgs production in vector boson fusion, at NLO QCD accuracy. It

Probing anomalous Higgs boson couplings in Higgs plus jet production at NLO QCD with full mt-dependence

open access: yesJournal of High Energy Physics
We present NLO QCD results for Higgs boson production in association with one jet, including anomalous Higgs-top and effective Higgs-gluon couplings within non-linear Effective Field Theory (HEFT), as well as the full top quark mass dependence.

Multi-Higgs boson production with anomalous interactions at current and future proton colliders

open access: yesJournal of High Energy Physics
We investigate multi-Higgs boson production at proton colliders, in a framework involving anomalous interactions, focusing on triple Higgs boson production.

Polarized Z cross sections in Higgsstrahlung for the determination of anomalous ZZH couplings

open access: yesPhysics Letters B, 2023
The production of a Higgs boson in association with a Z at an electron-positron collider is one of the cleanest methods for the measurement of the couplings of the Higgs boson.

Anomalous couplings in Higgs-boson pair production at approximate NNLO QCD

open access: yesJournal of High Energy Physics, 2021
We combine NLO predictions with full top-quark mass dependence with approximate NNLO predictions for Higgs-boson pair production in gluon fusion, including the possibility to vary coupling parameters within a non-linear Effective Field Theory framework ...

Stringent bounds on HWW and HZZ anomalous couplings with quantum tomography at the LHC

open access: yesJournal of High Energy Physics, 2023
Quantum tomography provides the full reconstruction of the density matrix of a state. We use it to study the Higgs boson decay into weak gauge bosons. Anomalous couplings beyond the Standard Model can be constrained by means of observables easily defined

Primary observables for indirect searches at colliders

open access: yesJournal of High Energy Physics, 2023
We consider the complete set of observables for collider searches for indirect effects of new heavy physics. They consist of SU(3)C × U(1)EM invariant interaction terms/operators that parameterize deviations from the Standard Model.
