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.

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.

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.

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

open access: yesJournal 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

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

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.

Positivity bounds at one-loop level: the Higgs sector

open access: yesJournal of High Energy Physics, 2023
In this paper, we promote the convex cone method of positive bounds from tree level to loop level. This method is general and can be applied to obtain leading s 2 positivity bounds on the forward scattering process in the standard model effective field ...

Portraying double Higgs at the Large Hadron Collider II

open access: yesJournal of High Energy Physics, 2022
The Higgs potential is vital to understand the electroweak symmetry breaking mechanism, and probing the Higgs self-interaction is arguably one of the most important physics targets at current and upcoming collider experiments.
