Abstract We show that baryons carrying heavy flavors, such as strangeness and charm, can be described by bound states of the corresponding heavy mesons in the background field of the basic SU(2) skyrmion. This method is quantitatively successful to O(Nc0), in the sense of the large-Nc expansion, but at O(1/Nc) it experiences problems associated with our lack of knowledge of higher-derivative terms in the Skyrme action. We derive a model-independent mass relation for strange baryons which is in…

Toward bound-state approach to strangeness in holographic QCD
Abstract An approach to realize a hyperon as a bound-state of a two-flavor baryon and a kaon is considered in the context of the Sakai–Sugimoto model of holographic QCD, which approach has been known
Bound State Approach for Strange Dibaryons in the Skyrme Model
Abstract The bound state approach to strange dibaryons in the Skyrme model is extended to baryon number n > 1. Kaon bound states are obtained in a (variational) axially symmetric SU (2) skyrmion
Strange dibaryons in the skyrme model
Abstract The bound state approach to strange dibaryons in the Skyrme model is extended to baryon number n > 1. Kaon bound states are obtained in a (variational) axially symmetric SU(2) Skyrmion
Strange dibaryons in the simplified skyrme model
Abstract We show that the bound-state approach to the strange dibaryons in the Skyrme model can be considerably simplified by omitting the Skyrme stabilizing term proportional to e−2 and using the
Strangeness in the Skyrme Model
These lectures review the fundamentals of the Skyrme model of baryons and its relationship with the non-relativistic quark model and the large-N QCD. Special emphasis is placed on the problems the
Charmed baryons as soliton - D meson bound states
We show that charmed baryons are remarkably well described as bound states of the D mesons with a soliton. The scheme exploits the isospin-spin transmutation that takes place when a doublet
Heavy baryons in a topological soliton model
Abstract It is shown that the bound state approach to strange hyperons can be successfully extended to the description of heavy flavoured baryons. The scheme exploits the isospin-spin transmutation
Meson-hyperon coupling constants in the bound-state approach to strangeness
Abstract Meson-hyperon coupling constants are calculated using the bound-state approach to strangeness of Callan and Klebanov. In this model K and π mesons are treated in entirely different ways, and
Hyperons as bound states in the skyrme model
Abstract We show that the bound-state approach to the hyperons in the Skyrme model developed by Callan, Klebanov and Hornbostel can be formulated in a way that avoids the square root of the SU(2)
Hyperon and nucleon structure in an SU(3) skyrme model
Abstract By incomparating the vector-meson-motivated sixth-order derivative term, the masses of hyperons can be described well with a reasonable value of F π in the framework of the exact

Doubly strange dibaryon in the chiral model
It is shown that the chiral model with SU(3) flavor symmetry predicts a dibaryon state of low mass M (Mroughly-equal2x2 GeV). It is electrically neutral and is an SU(3) singlet with J/sup P/ = 0/sup
