Super Yang–Mills with partially non-linear extended supersymmetry

Physics Letters B
We discuss 4D N=2 non-abelian gauge theories where one supersymmetry is preserved while the other one is spontaneously broken and non-linearly realized. The goldstino resides in a Maxwell multiplet of the Bagger–Galperin type.

Generation of Electric Current by Magnetic Field at the Boundary: Quantum Scale Anomaly Versus Semiclassical Meissner Current Outside of the Conformal Limit

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.

On the origin of the enhancement of CP-violating charge asymmetries in $K^\pm \to3\pi$ decays predicted from chiral theory

, 1993
We present an analysis of the enhancement of CP-violating charge asymmetries in $K^±→3π$ decays. Calculations of decay amplitudes are performed on the basis of bosonized strong and weak lagrangians derived from QCD-motivated quark lagrangians.

Anomalous effective lagrangians and vector resonance models [PDF]

, 1993
Chiral lagrangians including vector resonances have been shown to saturate the finite part of some of the counterterms needed to regularize ordinary one-loop effective lagrangians of pseudoscalar interactions with external currents.

Dualities and inhomogeneous phases in dense quark matter with chiral and isospin imbalances in the framework of effective model

Journal of High Energy Physics, 2019
It has been shown in [15, 70] in the framework of Nambu-Jona-Lasinio model with the assumption of spatially homogeneous condensates that in the large-N c limit (N c is the number of quark colours) there exist three dual symmetries of the thermodynamic ...

Flavored extended instanton in QCD

Journal of High Energy Physics, 2020
We discuss new flavored space-like defects in confined QCD which can be considered as the Euclidean extended instantons carrying the topologically quantized currents.

A new theory framework for the electroweak radiative corrections in K l3 decays

Journal of High Energy Physics, 2020
We propose a new theory framework to study the electroweak radiative corrections in K l3 decays by combining the classic current algebra approach with the modern effective field theory. Under this framework, the most important O $$ \mathcal{O} $$ (G F α)

Reconciling threshold and subthreshold expansions for pion–nucleon scattering

Physics Letters B, 2017
Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion–nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects enhanced by large low-energy constants.

Remarks on the pion–nucleon σ-term

Physics Letters B, 2016
The pion–nucleon σ-term can be stringently constrained by the combination of analyticity, unitarity, and crossing symmetry with phenomenological information on the pion–nucleon scattering lengths. Recently, lattice calculations at the physical point have
