The Large N(c) renormalization group
- Physics
- 1995
In this chapter1, we review how effective theories of mesons and baryons become exactly soluble in the large-N c limit. We start with a generic hadron Lagrangian constrained only by certain…
Electro-excitation amplitudes of the Δ-isobar in the Skyrme model
- Physics
- 1997
Electro magnetic transition form factors for the excitation of the Δ33-resonance are evaluated in the Skyrme model. They crucially rely on rotationally induced deformations of the hedgehog soliton…

Large-N QCD baryon dynamics: exact results from its relation to the static strong-coupling theory
- Physics
- 1984
Starting from the large-$N$ power counting which suggests that the baryons are QCD solitons, the authors derive an exact large-$N$ equation identical to the so-called bootstrap condition of static…
It=Jt rule: A new large-Nc selection rule for meson-baryon scattering.
- PhysicsPhysical review letters
- 1988
Quasielastic meson-baryon scattering is reformulated, in t-channel language (meson exchange) instead of s-channel language (baryon-resonance formation), using skyrmion methods. A new selection rule…
Baryon Number in Chiral Bag Models
- Physics
- 1983
When a massless, isospinor Dirac field is confined to a finite region of space by means of a chiral boundary condition parametrized by an angle theta, the baryon number of the vacuum is shown to be…
