The lagrangian formulation of chiral scalars
Physics Letters B, 1987 Abstract The lagrangian proposed by Siegel describing left- or right-moving scalars in two dimensions is analysed. The existence of anomalies is pointed out and a modification of the lagrangian leading to the elimination of anomalies is proposed. The generalization for chiral scalars defined on an arbitrary Riemann surface is discussed.

Off-Shell Scalar Supermultiplet in the Unfolded Dynamics Approach
, 2014 We show how manifestly supersymmetric action for Wess-Zumino model can be constructed within the unfolded dynamics approach. The off-shell unfolded system for N = 1, D = 4 scalar supermultiplet is found. The action is presented in the form of integral of

Low-energy interactions of Nambu-Goldstone bosons with $D$ mesons in covariant chiral perturbation theory [PDF]
, 2010 We calculate the scattering lengths of Nambu-Goldstone bosons interacting with $D$ mesons in a covariant formulation of chiral perturbation theory, which satisfies heavy-quark spin symmetry and analytical properties of loop amplitudes.

An Algebraic Roadmap of Particle Theories
Annalen der Physik, Volume 537, Issue 4, April 2025.Algebraic models of particle physics are often met with recurring obstacles. An ideal algebraic model should ‘1e conform to the Coleman‐Mandula theorem, ‘2e evade familiar fermion doubling problems, ‘3e naturally explain the Standard Model's chirality, ‘4e exclude B‐L gauge symmetry at low energy, and ‘5e explain the existence of three generations ...

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.

New classes of summable Skyrmions
, 1993 We introduce two new classes of summable Skyrmions. The Lagrangians they originate from are explicitely constructed. We also analyse how some models could be solve. Exact solutions are found for Skyrme-like toy models.Comment: 9 pages, revtex v3, EP-CPTh.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Radiative decays of the doubly charmed baryons in chiral perturbation theory
, 2017 We have systematically investigated the spin-$\frac{3}{2}$ to spin-$\frac{1}{2}$ doubly charmed baryon transition magnetic moments to the next-to-next-to-leading order in the heavy baryon chiral perturbation theory (HBChPT).

Micropolar Elastoplasticity Using a Fast Fourier Transform‐Based Solver
International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.ABSTRACT This work presents a micromechanical spectral formulation for obtaining the full‐field and homogenized response of elastoplastic micropolar composites. A closed‐form radial‐return mapping is derived from thermodynamics‐based micropolar elastoplastic constitutive equations to determine the increment of plastic strain necessary to return the ...

The dual properties of chiral and isospin asymmetric dense quark matter formed of two-color quarks
Journal of High Energy Physics, 2020 In this paper the phase structure of dense baryon matter composed of u and d quarks with two colors has been investigated in the presence of baryon μ B , isospin μ I and chiral isospin μ I5 chemical potentials in the framework of Nambu-Jona-Lasinio model
