Recent Status of the Chiral Bag Model

Abstract

In this note, recent status of the chiral bag model is presented. As it combines the MIT quark bag model and the Skyrme model, the chiral bag model interpolates the two models smoothly as a function of the chiral bag radius R. The correct limit of R→∞ is reproduced by including the higher order terms in the Ω expansion of the cranking method. It resolves the so-called small gA problem in a class of models where the semiclassical method is used.
