Notes on Parameterized Energy Pathways in the Ocean: Insights From Stochastic and Deterministic Kinetic Energy Injection

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 5, May 2025.
Abstract Accurately representing ocean dynamics across interacting scales remains a challenge in numerical modeling. This study examines mesoscale eddy parameterization in eddy‐permitting ocean models by incorporating novel stochastic perturbations and comparing them with a well‐tested dynamic kinetic energy backscatter scheme.

Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions

Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

QUARK STRUCTURE OF PSEUDOSCALAR MESONS [PDF]

International Journal of Modern Physics A, 2000
I review to which extent the properties of pseudoscalar mesons can be understood in terms of the underlying quark (and eventually gluon) structure. Special emphasis is put on the progress in our understanding of η–η′ mixing. Process-independent mixing parameters are defined, and relations between different bases and conventions are studied.

Nonlinear Vortex Dichroism in Chiral Molecules

Advanced Optical Materials, Volume 13, Issue 3, January 24, 2025.
Chiral molecules are shown to absorb two photons from a linearly polarized Laguerre–Gaussian vortex beams at different rates depending on the sign and magnitude of orbital angular momentum: nonlinear vortex dichroism. This new form of nonlinear optical activity is shown to have many remarkable properties, including novel access to structural ...

Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
Decays B⟶DPℓ+νℓ(ℓ = e, μ, τ) with the nonresonance, the charmed vector resonances, the charmed scalar resonances, and the charmed tensor resonances are explored by using the SU(3) flavor symmetry approach. Firstly, the decay amplitudes of different modes are related by the SU(3) flavor symmetry.

Combined search for anomalous pseudoscalar HVV couplings in VH(H→bb‾) production and H→VV decay

Physics Letters B, 2016
A search for anomalous pseudoscalar couplings of the Higgs boson H to electroweak vector bosons V (=W or Z) in a sample of proton–proton collision events corresponding to an integrated luminosity of 18.9 fb−1 at a center-of-mass energy of 8 TeV is ...

Global constraints on neutral-current generalized neutrino interactions

Journal of High Energy Physics, 2021
We study generalized neutrino interactions (GNI) for several neutrino processes, including neutrinos from electron-positron collisions, neutrino-electron scattering, and neutrino deep inelastic scattering.

Tensor Condensate Accompanied by Chiral Transition in a Strong Magnetic Field

Advances in High Energy Physics, Volume 2025, Issue 1, 2025.
We investigate tensor condensates and chiral condensates in the (2 + 1)‐flavor Nambu–Jona–Lasinio model at finite temperature and density in the presence of a strong magnetic field. The emergence of the tensor condensate is attributed to the four‐fermion interaction.

One-loop pseudoscalar mass in a 2HDM with a Z 3 symmetry

Journal of High Energy Physics
A two-Higgs doublet model with a discrete Z 3 symmetry acquires, in its scalar and gauge sectors, an accidental continuous U(1) symmetry. One therefore finds, after spontaneous symmetry breaking of those symmetries, that a massless pseudoscalar arises ...

Distinguishing scalar from pseudoscalar Higgs production at the LHC

, 2002
In this letter we examine the production channels for the scalar or pseudoscalar Higgs plus two jets at the CERN Large Hadron Collider (LHC). We identify possible signals for distinguishing between a scalar and a pseudoscalar Higgs boson.Comment: 7 pages,
