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.

Anomalous Higgs Couplings [PDF]

open access: yesInternational 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 Yukawa Couplings [PDF]

open access: yesEPL (Europhysics Letters), 2014
In the standard model, the Higgs boson $h$ couples to the quarks and charged leptons according to the well-known formula $(m_\psi/v) h \bar{\psi}\psi$, where $\psi$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value.

Anomalous Higgs Couplings at the LHeC [PDF]

open access: yesNuclear Physics B, 2013
The discovery of Higgs boson plays a crucial role in understanding the electroweak symmetry breaking sector. From now on, solving the dynamics of this sector needs precision measurements of the couplings of the Higgs boson to the standard model particles.

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

open access: yesPhysical 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.

Electroweak baryogenesis with anomalous Higgs couplings [PDF]

open access: yesJournal of High Energy Physics, 2016
In non-linear realisation of the electroweak gauge symmetry, the LHC Higgs boson can be assumed to be a singlet under [Formula: see text]. In such scenario, the Standard Model particle content can be kept but new sets of couplings are allowed. We identify a range of anomalous Higgs cubic and the [Formula: see text]-violating Higgs-top quark couplings ...

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

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

open access: yesThe 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).
