Pentaquark in the Skyrme Model

Abstract

The mass of the newly discovered pentaquark is calculated within the framework of the SU(3) Skyrme Model. Various estimates based on the \emph{model independent} approach are compared with the model results and with the Chiral Quark Model. Our discussion shows that ${\Theta }^{+}$ is light with the mass of the order 1.5 GeV.

12 pages, 4 figures. In v2 Numerical error in Eq.(19) corrected. The resulting mass of N* is now smaller by 2%. This can be seen in the replaced Fig.1b. Minor typos corrected. All conclusions and discussion remains unchanged. In v3 reference added
