N = 4 SUPERSYMMETRIC LAGRANGIAN FOR SELF-DUAL FIELDS [PDF]

, 2020
The lagrangian for the N = 4 supersymmetric extension of the chiral boson is obtained from a truncation of the N = 4 spinning string. This lagrangian completes the list given by Siegel of lagrangians for the chiral boson and its supersymmetric extensions,

Chiral oscillations in finite time quantum field theory

European Physical Journal C: Particles and Fields
We demonstrate how chiral oscillations of a massive Dirac field can be described within quantum field theory using a finite-time interaction picture approach, where the mass term in the Lagrangian is treated as a perturbative coupling between massless ...

Towards a lattice calculation of the coefficients of the QCD chiral Lagrangian

, 1997
We discuss a general strategy to compute the coefficients of QCD chiral Lagrangian by using the lattice regularization of QCD with Wilson fermions. This procedure requires the introduction of an effective Lagrangian for lattice QCD as an intermediate ...

Axion production in the η → ππa decay within SU(3) chiral perturbation theory

Journal of High Energy Physics
We study the axion and axion-like particle production from the η → ππa decay within the SU(3) chiral perturbation theory up to the one-loop level. The conventional SU(3) chiral low energy constants are found to be able to reabsorb all the divergences ...

Electromagnetic interactions in a chiral effective lagrangian for nuclei

Annals of Physics, 2007
Electromagnetic (EM) interactions are incorporated in a recently proposed effective field theory of the nuclear many-body problem. Earlier work with this effective theory exhibited EM couplings that are correct only to lowest order in both the pion fields and the electric charge.

Learning holographic QCD with unflavored meson spectra

Journal of High Energy Physics
We develop a data-driven neural network framework to reconstruct the five-dimensional background geometry, the dilaton potential, and the chiral-symmetry-breaking scalar potential of holographic QCD from hadron mass spectra. Framed as an inverse problem,

Role of Light Vector Mesons in the Heavy Particle Chiral Lagrangian [PDF]

, 1992
We give the general framework for adding light vector particles to the heavy hadron effective chiral Lagrangian. This has strong motivations both from the phenomenological and aesthetic standpoints. An application to the already observed D \rightarrow \

Calculation of the chiral Lagrangian coefficients with light vector mesons [PDF]

We calculate the coefficients in the effective chiral Lagrangian from QCD, which includes pseudo-scalar mesons and vector mesons (with hidden symmetry), up to O(p4). This encompasses both the normal and anomalous parts.
