Multi-Higgs boson production with anomalous interactions at current and future proton colliders

Journal of High Energy Physics
We investigate multi-Higgs boson production at proton colliders, in a framework involving anomalous interactions, focusing on triple Higgs boson production.

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 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 $m_ψ/v$.

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

Primary observables for indirect searches at colliders

Journal 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.

Constraining anomalous couplings in the gauge-Higgs sector at high-energy colliders [PDF]

, 2022
Several physical phenomena suggest that the Standard Model is not the ultimate theory possible for describing Nature, and looking for deviations from the theory prediction might be a hint for physics beyond the Standard Model.

Positivity bounds at one-loop level: the Higgs sector

Journal 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 ...
