Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

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 ...

Is there new particle running in the loop-induced Hγγ and Hgg vertex?

Physics Letters B, 2017
Loop-induced Hgg and Hγγ coupling play an important role in the Higgs production and decay at the LHC. These vertices can be affected by various New Physics contributions, including new particles, anomalous Yukawa couplings, and so on.

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

, 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.

Is There a Future for Stochastic Modeling in Business and Industry in the Era of Machine Learning and Artificial Intelligence?

Applied Stochastic Models in Business and Industry, Volume 41, Issue 2, March/April 2025.
ABSTRACT The paper arises from the experience of Applied Stochastic Models in Business and Industry which has seen, over the years, more and more contributions related to Machine Learning rather than to what was intended as a stochastic model. The very notion of a stochastic model (e.g., a Gaussian process or a Dynamic Linear Model) can be subject to ...

Probing anomalous gauge-Higgs couplings using Z boson polarization at e+e− colliders

Nuclear Physics B, 2020
We study possible new physics interactions in the $ZZH$ vertex contributing to the Higgsstrahlung process $e^+ e^- \to ZH$ at proposed future $e^+e^-$ colliders using the polarization of the $Z$ as a probe. We calculate the spin density matrix of the $Z$ for the process and determine the eight independent polarization parameters of the $Z$ boson which ...

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Sensitivity study of anomalous HZZ couplings at a future Higgs factory *

Chinese Physics C, 2019
Abstract We study the sensitivity of constraining the model independent H ZZ coupling based on the effective theory up to dimension-6 operators at a future Higgs factory. Using the current conceptual design parameters of the Circular Electron Positron Collider, we give the experimental limits for the model independent ...

Late Cretaceous to Oligocene source‐to‐sink system in Central Zealandia: implications for exhumation, paleogeography and Cenozoic Australia‐Pacific plate boundary evolution

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 1, Page 206-240, March 2025.
ABSTRACT U–Pb, and zircon and apatite fission track data provide a powerful means to characterise the Late Cretaceous to Late Oligocene source‐to‐sink system and continent evolution in central Zealandia. Our dataset includes samples from potential source rocks in northwest Nelson (Takaka and Buller terranes; Karamea, Tobin, Darran and Separation Point ...
