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

Journal 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.

Note on anomalous Higgs-boson couplings in effective field theory

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 ...

Higgs windows to new physics through d = 6 operators: Constraints and one-loop anomalous dimensions

Journal of High Energy Physics, 2013
The leading contributions from heavy new physics to Higgs processes can be captured in a model-independent way by dimension-six operators in an effective Lagrangian approach.

Probing anomalous couplings using di-Higgs production in electron–proton collisions

Physics Letters B, 2017
A proposed high energy Future Circular Hadron-Electron Collider would provide sufficient energy in a clean environment to probe di-Higgs production. Using this channel we show that the azimuthal angle correlation between the missing transverse energy and the forward jet is a very good probe for the non-standard $hhh$ and $hhWW$ couplings.

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.

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

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 ...

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
