S-Wave Meson-Nucleon Interactions and the Meson Mass in Nuclear Matter From Chiral Effective Lagrangians [PDF]
, 1995 Chiral effective lagrangians may differ in their prediction of meson-nucleon scattering amplitudes off-meson-mass-shell, but must yield identical S-matrix elements.

An effective strong-coupling theory of composite particles in UV-domain
Journal of High Energy Physics, 2017 We briefly review the effective field theory of massive composite particles, their gauge couplings and characteristic energy scale in the UV-domain of UV-stable fixed point of strong four-fermion coupling, then mainly focus the discussions on the decay ...

Hard thermal loops and chiral Lagrangians [PDF]
Physical Review D, 1998 Chiral symmetry is used as the guiding principle to derive hard thermal loop effects in chiral perturbation theory. This is done by using a chiral invariant background field method for the non-linear sigma model and the Wess-Zumino-Witten lagrangian, with and without external vector and axial vector sources.

Skyrmions and effective Lagrangians [PDF]
, 1989 The need to model quantum chromodynamics (QCD) at low energy is emphasized. An outline of the1/NC expansion of QCD, for large NC, shows the deep link between the Skyrme effective Lagrangian and QCD.

Flavor decomposition of the pion-nucleon σ-term
Journal of High Energy Physics, 2019 We re-analyze the flavor decomposition of the pion-nucleon σ-term in the framework of baryon chiral perturbation to fourth order. We employ a covariant and the heavy baryon framework including also the low-lying decuplet.

Advanced Physics Research, Volume 4, Issue 7, July 2025.The paper discusses the role of scale anomaly in generating edge electric currents via the scale magnetic effect in scalar electrodynamics. Although the boundary electric current is much weaker than the Meissner current induced in superconducting materials, the scale anomaly can enhance conductivity near the boundary of the material.

Dynamical axions and gravitational waves
Journal of High Energy Physics, 2019 In this paper we explore the possibility of observable gravitational waves as a manifestation of the QCD axion dynamics. In particular, we focus on dynamical axion models which solve the strong CP problem, and include the confinement of a QCD-like gauge ...

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 ...
