Abstract: (Elsevier)
We review the chiral bag model for the nucleon at low energy. The model is a hybrid model of quark and meson degrees of freedom, interpolating the two limits of the Skyrme model at R → 0 and the MIT bag model at R → ∞, where R is the bag radius. Baryon number one ( B = 1) solutions are obtained in the semiclassical method, where the nucleon is regarded as a slowly rotating hedgehog. We investigate static properties of the nucleon such as masses and magnetic moments as functions of R , first in the original chiral bag model and second in the models with vector mesons. We find a reasonably good description for the nucleon in both cases at an intermediate bag radius R ~ 0.6 fm. Results of the model calculations are then re-derived using a group theoretical method in the large- N c limit.- 12.39.Ba
