Large Nc QCD and Models of Exotic Baryons

TL;DR

This paper discusses the theoretical modeling of exotic baryons within large Nc QCD, highlighting issues with the assumptions used in quantizing chiral soliton models and questioning their validity.

Contribution

It critically examines the quantization techniques of chiral soliton models in large Nc QCD, pointing out unverified dynamical assumptions.

Findings

Conventional quantization methods rely on unjustified dynamical assumptions.

Exotic baryons predicted by chiral soliton models may lack solid theoretical foundation.

The validity of these models in describing experimental resonances is questionable.

Abstract

Exotic baryons have been predicted in the context of the chiral soliton model. These states have been identified with strangeness +1 resonances reported in a number of experiments. In this talk it is pointed out that the technique used to quantize these solitons in most conventional treatments depends on dynamical assumptions beyond those in standard large Nc physics. These additional assumptions have never been justified.
