Anisotropy of the Characteristic Critical Fields and Length Scales of Sr1 − xKxFe2As2 Superconductor

Advanced Physics Research, Volume 4, Issue 10, October 2025.
The upper critical magnetic field parallel to ab‐plane (HC2∥ab${\mathrm{H}}_{C2\Vert \textit{ab}}$) and upper critical magnetic field parallel to ‐caxis (HC2∥c$\mathrm{H}_{C2}^{\parallel c}$) decrease with temperature increase and vanish at the critical temperature. The angular dependence of upper critical magnetic field (HC2) show anisotropic behavior.

Exploratory calculation of the rare hyperon decay Σ+ → pℓ + ℓ − from lattice QCD

Journal of High Energy Physics
The rare hyperon decay Σ+ → pℓ + ℓ − is a flavour-changing neutral current process mediated by an s → d transition that occurs only at loop level within the Standard Model.

Perturbative spacetimes from Yang-Mills theory

Journal of High Energy Physics, 2017
The double copy relates scattering amplitudes in gauge and gravity theories. In this paper, we expand the scope of the double copy to construct spacetime metrics through a systematic perturbative expansion.

Operator Analysis for the Higgs Potential and Cosmological Bound on the Higgs-Boson Mass

, 1993
Using effective lagrangian, we examine the impacts of new physics on the electroweak baryogenesis. By analysing the high dimensional operators relevent to the Higgs potential we point out that the Higgs mass bound required by electroweak baryogenesis can

Higgs physics: An historical perspective [PDF]

AIP Conference Proceedings, 1997
``Weakly-coupled'' and ``strongly-coupled'' models of electroweak symmetry breaking are introduced by analogy with the Fermi theory of the weak interaction and the low-energy interaction of pions, respectively. The implications of these two classes of models for colliders beyond the LHC and NLC are discussed.

Higgs physics at CLIC [PDF]

Proceedings of The 39th International Conference on High Energy Physics — PoS(ICHEP2018), 2019
The Compact Linear Collider (CLIC) is a mature option for a future electron-positron collider operating at centre-of-mass energies of up to 3 TeV. CLIC will be built and operated in a staged approach with three centre-of-mass energy stages currently assumed to be 380 GeV, 1.5 TeV and 3 TeV.

Anatomizing Exotic Production of the Higgs Boson

, 2014
We discuss exotic production modes of the Higgs boson and how their phenomenology can be probed in current Higgs analyses. We highlight the importance of differential distributions in disentangling standard production mechanisms from exotic modes.

Coherent states, background fields, and double copy

Journal of High Energy Physics
We show that scattering amplitudes on any gauge theory background admitting a coherent state description double copy to amplitudes in a curved spacetime.
