High energy vector boson scattering in four-body final states to probe Higgs cubic, quartic, and HEFT interactions

Journal of High Energy Physics
We compute the energy scales of perturbative unitarity violation in various 2 → 4 vector boson scattering (VBS) processes and compare them to lower multiplicity processes.

Deep Convective Trace Gas Transport to the UTLS: Highlighting Remote Sensing and Modeling Challenges With ACCLIP Campaign In Situ CO Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract China is a major source of anthropogenic emissions, with important implications for chemical composition and aerosol processes in the upper troposphere and lower stratosphere (UTLS), particularly within the Asian Summer Monsoon (ASM) anticyclone.

Comparative Gas‐Brine Relative Permeability of H2, N2, and CO2 Under Subsurface Storage Conditions

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Gas‐brine relative permeability controls subsurface gas storage, including underground hydrogen and CO2 storage. Here, we measure steady‐state gas‐brine relative permeabilities for H2, N2, and CO2 in a sandstone core at 0.1–6 MPa under identical conditions.

How large are hadronic contributions to h → γγ?

Journal of High Energy Physics
The decay of the Higgs boson into two photons, h → γγ, is a loop-induced process within the Standard Model, predominantly mediated by loops of W bosons and top quarks.

Measurement of cross sections and couplings of the Higgs Boson in bosonic decay channels with the ATLAS detector

EPJ Web of Conferences, 2018
After the discovery of the Higgs boson, the measurement of its properties are of particular importance. In this paper, measurement of the cross sections and couplings of the Higgs boson in bosonic decay channels with the ATLAS detector are presented ...

Enhanced sensitivity to the H → Zγ → ℓ + ℓ − γ decay at the LHC using machine learning and novel kinematic observables

Journal of High Energy Physics
At LHC energies, the Drell-Yan (Z/γ *) processes have a substantially large cross section. Their di-lepton (ℓ + ℓ − ) final state contributes significantly to many resonant signal regions, making them one of the dominant backgrounds in numerous physics ...

A CP 2 $$ {\mathbbm{CP}}^2 $$ SMEFT

Journal of High Energy Physics
An extension of the Standard Model is proposed, where the Higgs field is valued in the complex projective plane CP 2 $$ {\mathbbm{CP}}^2 $$ , rather than ℂ 2. Its geometry is consistent with U(2) ≃ (SU(2) × U(1))/ℤ 2 electroweak gauge symmetry.

Combined Analysis of the CP Properties of The Higgs Boson in Effective Higgs Lagrangian

, 2014
CP violation effects of the Higgs stem from not only CP-violation interactions but also an ambiguous defined CP state. The two CPV sources are coherently studied based on an effective Higgs Lagrangian. The constraints from unitarity limits for $WW$ and $ZZ$ scatterings are proposed to restrict Higgs couplings to weak gauge bosons.

Matching the real Higgs triplet extension of Standard Model to HEFT

Journal of High Energy Physics
Focusing on the bosonic sector, we make a first matching of the real Higgs triplet extension (RHTE) of the standard model to the Higgs effective field theory (HEFT), which is also known as electroweak chiral Lagrangian (EWChL), including effects of the ...

Non-Resonant Di-Higgs Searches at the Large Hadron Collider with the CMS Experiment

Particles
Investigating the production of Higgs boson pairs (HH) at the LHC provides critical insights into the self-interaction properties of the Higgs boson, representing an essential verification of the Standard Model and contributing to our understanding of ...
