Instantons and chiral Lagrangian
Physical Review D, 1989We 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, 1985We 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, 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. This formalism

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.

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//

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
