Derivation of effective chiral Lagrangian involving PSGB and vector bosons from QCD
TLDR
In this paper, the effective chiral Lagrangian for a matter field content consisting of pseudo-scalar Goldstone bosons and vector bosons with hidden symmetry is derived from the underlying QCD theory.Abstract:
The effective chiral Lagrangian for a matter field content consisting of pseudo-scalar Goldstone bosons and vector bosons (with hidden symmetry) is derived from the underlying QCD theory. No approximations are made. All the free parameters of the effective chiral Lagrangian are expressed in terms of QCD-based Green's functions. These may be regarded as the QCD definitions of these Lagrangian coefficients.read more

Anomalous action in gauge invariant, nonlocal, dynamical quark model

TL;DR: Anomalous sector of chiral Lagrangian is calculated in a gauge invariant, nonlocal, dynamical quark model in this article, where the Wess-Zumino term is proved coming from two kinds of sources, one is independent of and another dependent on dynamically quark self energy Sigma(k(2)).

Chiral effective Lagrangian for heavy-light mesons from QCD
TL;DR: In this paper, the chiral effective Lagrangian for heavy-light mesons in the heavy quark limit was derived from QCD under proper approximations, and the low energy constants in the effective lagrangian were expressed in terms of the light quark self-energy.

Chiral effective Lagrangian for heavy-light mesons from QCD: $1/m_{Q}$ correction
TL;DR: In this article, the authors derived the low energy constants in the effective Lagrangian for heavy-light mesons from QCD under proper approximations and showed that the results of pion decay constant and the masses of heavy light mesons are improved coherently compared to that obtained in the heavy quark limit.

New Terms for Compact Form of Electroweak Chiral Lagrangian
TL;DR: The compact form of the electroweak chiral Lagrangian is a reformulation of its original form and is expressed in terms of chiral rotated electroweak gauge fields, which are crucial for relating the information of underlying theories to the coefficients of the low-energy effective Lagrangians as mentioned in this paper.
