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

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.

The Mesonic Chiral Lagrangian of Order [PDF]
, 2007 : We construct the effective chiral Lagrangian for chiral perturbation theory in the mesonic even-intrinsic-parity sector at order p 6 . The Lagrangian contains 112 in principle measurable + 3 contact terms for the general case of n light flavours, 90 ...

QCD chiral Lagrangian on the lattice, strong coupling expansion, and Ward identities with Wilson fermions [PDF]
, 1997 We discuss a general strategy to compute the coefficients of the QCD chiral Lagrangian using lattice QCD with Wilson fermions. This procedure requires the introduction of a lattice chiral Lagrangian as an intermediate step in the calculation.

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-

Lagrangians for massive Dirac chiral superfields
Nuclear Physics B, 2016 A variant for the superspin one-half massive superparticle in $ 4D $, $ \mathcal{N}=1 $, based on Dirac superfields, is offered. As opposed to the current known models that use spinor chiral superfields, the propagating fields of the supermultiplet are those of the lowest mass dimensions possible: scalar, Dirac and vector fields.

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.
