Strong decays of radially excited mesons in a chiral approach

, 2009
We study radial excitations of pseudoscalar and vector (q bar q) mesons within a chiral approach. We derive a general form for a chiral Lagrangian describing processes involving excited pseudoscalar and vector mesons.

Topological Quasiparticles of Light: From Spin‐Orbit Coupling to Photonic Skyrmions

Laser &Photonics Reviews, Volume 19, Issue 24, December 17, 2025.
This review summarizes recent advances in photonic skyrmions, emphasizing the central role of spin–orbit coupling in their formation. The review discusses how spin–orbit interactions generate skyrmionic textures, examines modulation strategies for their dynamic control, and provides an overview of emerging directions and opportunities where these ...

Production of vector resonances at the LHC via WZ-scattering: a unitarized EChL analysis

Journal of High Energy Physics, 2017
In the present work we study the production of vector resonances at the LHC by means of the vector boson scattering WZ → WZ and explore the sensitivities to these resonances for the expected future LHC luminosities.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Axion-meson mixing in light of recent lattice η–η′ simulations and their two-photon couplings within U(3) chiral theory

Journal of High Energy Physics, 2023
We study the mixing of the QCD/QCD-like axion and light-flavor mesons π 0, η, η′ within the framework of U(3) chiral perturbation theory up to next-to-leading order in this work. The axion-meson mixing formulas are calculated order by order in the U(3) δ-

Simulations with different lattice Dirac operators for valence and sea quarks [PDF]

, 2002
We discuss simulations with different lattice Dirac operators for sea and valence quarks. A goal of such a "mixed" action approach is to probe deeper the chiral regime of QCD by enabling simulations with light valence quarks.

Effective Lagrangians and chiral random matrix theory [PDF]

Physical Review D, 1995
Recently, sum rules were derived for the inverse eigenvalues of the Dirac operator. They were obtained in two different ways: i) starting from the low-energy effective Lagrangian and ii) starting from a random matrix theory with the symmetries of the Dirac operator. This suggests that the effective theory can be obtained directly from the random matrix

Unification of Conformal and Fuzzy Gravities With Internal Interactions Resulting in SO(10) and a Possible Probe Through Stochastic Gravitational Wave Background

Fortschritte der Physik, Volume 73, Issue 9-10, October 2025.
Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.
