Search for anomalous couplings in the Higgs sector at LEP [PDF]
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2004 Anomalous couplings of the Higgs boson are searched for through the processes e+e− → Hγ , e+e− → e+e−H and e+e− → HZ. The mass range 70 GeV −1 of integrated luminosity collected with the L3 detector at LEP at centre-of-mass energies √s = 189–209 GeV. The

Anomalous Higgs couplings at the LHeC [PDF]
Nuclear 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. In this work, we investigate the constrains on the anomalous $HWW$ and $HWWγ$ couplings, described

Anomalous couplings in Higgs-boson pair production at approximate NNLO QCD [PDF]
Journal 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 ...

Higgs anomalous couplings, FCNC and LFV decays
, 2019 An overview of searches for the lepton flavor violating decays of the Higgs boson, and for flavor changing neutral currents in Hqt couplings are presented from the ATLAS. In addition, different approaches on the Higgs anomalous couplings to vector bosons from the two experiments are presented.

Note on anomalous Higgs-boson couplings in effective field theory [PDF]
Physics Letters B, 2015 We propose a parametrization of anomalous Higgs-boson couplings that is both systematic and practical. It is based on the electroweak chiral Lagrangian, including a light Higgs boson, as the effective field theory (EFT) at the electroweak scale $v$. This is the appropriate framework for the case of sizeable deviations in the Higgs couplings of order ...

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

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

Anomalous Higgs Yukawa couplings [PDF]
EPL (Europhysics Letters), 2014 In the standard model, the Higgs boson $h$ couples to the quarks and charged leptons according to the well-known formula $(m_ψ/v) h \barψψ$, where $ψ$ = quark (q) or lepton (l) and $v$ = 246 GeV is its vacuum expectation value. Suppose $m_ψ$ is of radiative origin instead, then the effective $h \barψψ$ Yukawa coupling will not be exactly $m_ψ/v$.
