Solitonic ground state in supersymmetric theory in background

Journal of High Energy Physics
A solitonic ground state called a chiral soliton lattice (CSL) is realized in a supersymmetric theory with background magnetic field and finite chemical potential.

The Changes in Properties of Hadrons in Nuclei and Nuclear Matter [PDF]

, 1995
The changes of hadron properties in dense and/or hot matter are discussed in terms of effective chiral Lagrangians with the parameters of the theory scaled in a simple way.

Strong decays of radially excited mesons in a chiral approach

, 2009
We study radial excitations of pseudoscalar and vector (q bar q) mesons within a chiral approach. We derive a general form for a chiral Lagrangian describing processes involving excited pseudoscalar and vector mesons.

Chiral lagrangians and WW scattering

Nuclear Physics B, 1991
Recently, it has been proposed that the scattering of strongly interacting longitudinal gauge bosons can be studied using chiral perturbation theory. By fitting the energy dependence of the scattering amplitudes in the energy region 0.5 TeV < √s < 1.2 TeV one is sensitive to the nature of electroweak symmetry breaking.

Chiral symmetry restoration at finite temperature in a model with manifest confinement

Physics Letters B
Multiple lattice evidences support the existence of a confining but chirally symmetric regime of QCD above the chiral symmetry restoration crossover at Tch≃155 MeV.

Chiral QED in Terms of Chiral Boson with a Generalized Fadeevian Regularization

, 2003
Chiral QED with a generalized Fadeevian regularization is considered. Imposing a chiral constraint a gauged version of Floranini-Jackiw lagrangian is constructed.

Sakai-Sugimoto model in an off-shell: Chiral Lagrangian to all orders

Journal of High Energy Physics
The Sakai-Sugimoto holographic model is famous for implementing the approximate chiral symmetry of QCD and reproducing the Chiral Lagrangian in a top-down approach.

Dynamical Computation on Coefficients of Electroweak Chiral Lagrangian from One-doublet and Topcolor-assisted Technicolor Models

, 2007
Based on previous studies deriving the chiral Lagrangian for pseudo scalar mesons from the first principle of QCD, we derive the electroweak chiral Lagrangian and build up a formulation for computing its coefficients from one-doublet technicolor model ...

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 ...

Lattice QCD and Chiral Lagrangians

, 1994
After a very brief review of the formalism of lattice gauge theories we show how one can calculate the parameters of the continuum chiral Lagrangians proceeding through the derivation of an effective lattice chiral Lagrangian as an intermediary step. The derivation is done in the strong coupling limit.
