Effective chiral Lagrangian with baryons
Physical Review D, 1987We 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, 1992Canonical 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.

The ATLAS and CMS collaborations at LHC have found a new boson compatible with the SM Higgs, with a mass of nearly \(M_h\simeq 125\,\mathrm{GeV}\). Furthermore, the most probable \(J^P\) quantum numbers are \(0^+\), and couplings with other particles are in agreement with the SM Higgs, although with moderate precision. Moreover, there is a mass gap for

Remarks on the dimension-four chiral Lagrangian
Physical Review D, 1986The 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//
