AbstractAbstract
[en] The Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence between theories in AdS space and conformal field theories in physical space-time provides as analytic, the semi-classical model for strongly-coupled QCD. In this work, we investigate properties of the octet baryon in the holographic model, calculate the coupling constant between π meson-octet baryon in the framework holographic model by considering the infrared-modified 5D conformal mass and Yukawa coupling of the bulk baryon field. Predictions of this model for the mass spectrum of the baryon octet are appropriate with the experimental value. It means the hard-wall AdS/QCD model is favorable for determining coupling constants between elementary particles

AbstractAbstract
[en] In this paper it is continued the geometrical investigation of certain symmetry-breaking mechanisms previously begun. It is considered first a geometrical interpretation of gauge field interactions with spinors when the spinor bundle structure is taken into account, and recovered in this way the ABJ anomaly. These ideas are then applied to a model of symmetry breaking within the light pseudoscalar-meson octet, and a formula for the Cabibbo angle theta is obtained which yields sintheta approx. 0.22804

AbstractAbstract
[en] We reexamine critically the chiral expansion for the baryon magnetic moments including the contributions from loops which involve intermediate octet and decuplet baryons. We find that, contrary to some claims, the nonanalytic loop contributions of orders ms1/2 and mslnms are of the same general size because of large coupling factors for the latter, and that the decuplet contributions are as large as the octet contributions and must be included in a consistent calculation. There is no clear evidence of the convergence of the chiral series. The adequacy of the theory will not be established until dynamical models are able to calculate the contributions from the counterterms that largely hide the loop effects in fits to the data. copyright 1998 The American Physical Society

AbstractAbstract
[en] The Goldberger-Treiman relation is shown to persist in the chiral limit at finite temperatures to O(T2). The T dependence of gA turns out to be the same as for Fπ, gA(T)=gA(0)(1-T2/12Fπ2), while gπNN is temperature independent to this order. The baryon octet scrD and scrF couplings also behave as Fπ if only pions are massless in the pseudoscalar meson octet

AbstractAbstract
[en] The author motivate the need for an analytical approach to calculating static properties of baryons that is firmly based on the underlying theory of strong interactions, quantum chromodynamics. We give a quantum mechanical example that illustrates the approach while introducing many of the methods to be applied. The sum rules are then used to calculate the masses and magnetic moments of the 1/2+ baryon octet in terms of phenomenological QCD parameters of the underlying theory. In the appendices we give the Fourier and Borel transforms used in this work as well as derive the perturbative and non-perturbative terms that are used in calculating the Wilson coefficients in the operator product expansion of the sum rules
