Mass Terms in the Skyrme Model

Kopeliovich, V.B.; Piette, B.; Zakrzewski, W.J.

Abstract

We consider various forms of the mass term for the Skyrme model and their implications on the properties of baryonic states. We show that modifications of the mass term, without changing the asymptotic behaviour of the profile function at large r, can considerably alter the mass term contributions. We argue that if one considers the Skyrme model as an effective model for nuclei, then the new mass terms should be taken to obtain a better description of the existing nuclei. In particular, we find that for some choices of the mass term, the formation of a shell like structure for large baryon number is energetically unfavourable for low baryon numbers and for the physical values of the pion mass.
