Search for anomalous couplings in the Higgs sector at LEP [PDF]

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2000
Anomalous couplings of the Higgs boson are searched for through the processes e^+ e^- -> H gamma, e^+ e^- -> e^+ e^- H and e^+ e^- -> HZ. The mass range 70 GeV < m_H < 190 GeV is explored using 602 pb^-1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies sqrt(s)=189-209 GeV. The Higgs decay channels

Higgs production constraints on anomalous fermion couplings [PDF]

open access: yesNuclear and Particle Physics Proceedings, 2016
Certain anomalous fermion-gauge boson couplings, such as the flavor diagonal anomalous color magnetic (CMDM) and color electric (CEDM) dipole moments of quarks are not fully gauge invariant under the SM. Restoring gauge invariance with an elementary Higgs doublet implies that they also contribute to Higgs boson production at the LHC and we study the ...

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.

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.
