Anomalous Higgs Couplings [PDF]

open access: greenInternational Journal of Modern Physics A, 1999
We review the effects of new effective interactions on the Higgs boson phenomenology. New physics in the electroweak bosonic sector is expected to induce additional interactions between the Higgs doublet field and the electroweak gauge bosons leading to ...

Anomalous Higgs Couplings as a Window to New Physics [PDF]

open access: greenPhysical Review D, 2013
The initial data on the production and decay of the Higgs boson reported significant deviations from the Standard Model (SM) expectations, prompting much speculation about its couplings to the other particles.

Anomalous gauge-boson couplings and the Higgs-boson mass [PDF]

open access: greenThe European Physical Journal C, 2004
We study anomalous gauge-boson couplings induced by a locally SU(2) x U(1) invariant effective Lagrangian containing ten operators of dimension six built from the boson fields of the Standard Model (SM) before spontaneous symmetry breaking (SSB).

Probing anomalous Higgs boson couplings in Higgs plus jet production at NLO QCD with full m t -dependence [PDF]

open access: diamondJournal 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.

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

open access: green, 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

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

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.

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.

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
