On the Chiral Effective Meson-Baryon Lagrangian at Third Order⋆ [PDF]

European Physical Journal A, 2006
We show that the recently constructed complete and "minimal" third-order meson-baryon effective chiral Lagrangian can be further reduced from 84 to 78 independent ...

Instantons and chiral Lagrangian

Physical Review D, 1989
We derive the chiral Lagrangian including instanton corrections in a consistent way. $\mathrm{CP}$ violation associated with the $\ensuremath{\theta}$ term in QCD is discussed in terms of this chiral Lagrangian. A particular emphasis is given to a phenomenological determination of ${m}_{u}$ and $\ensuremath{\theta}$.

Chiral Lagrangian of pseudoscalars and vectors

Physical Review D, 1985
We formulate a parity-invariant chiral Lagrangian which includes nonlinearly transforming vector mesons but no axial-vector mesons. It is gotten by a simple substitution from the Lagrangian involving a linearly transforming vector and axial-vector multiplet.

Effective chiral Lagrangian with baryons

Physical Review D, 1987
We use Ioffe's method of constructing (local) baryon field operators in terms of quarks to derive an effective chiral Lagrangian with U(3)\ifmmode\times\else\texttimes\fi{}U(3) symmetry consisting of the ${J}^{P}$${=(1/2)}^{+}$ baryon octet, the ${J}^{P}$${=(1/2)}^{\mathrm{\ensuremath{-}}}$ baryon nonet, and the pseudoscalar-meson nonet.

EQUIVALENCE OF THE QUADRATIC LAGRANGIANS FOR CHIRAL BOSONS

International Journal of Modern Physics A, 1992
Canonical quantization of both the Labastida-Pernici quadratic Lagrangian for two chiral bosons and the simplest chiral boson quadratic Lagrangian where the self-duality is imposed using a Lagrange-multiplier term is performed taking a proper account of the zero modes in the compact case, showing that they are exactly equivalent.

Remarks on the dimension-four chiral Lagrangian

Physical Review D, 1986
The profound fact that the dimension-four operators in the effective chiral Lagrangian, including quartic-derivative terms, are uniquely determined by the integration of spurious (nontopological) chiral anomalies has rich applications to low-energy hadron physics. The form factor f-italic/sub -/ and the Callan-Treiman relation in K-italic/sub l-italic//
