B=2 Oblate Skyrmions

Abstract

The numerical solution for the B=2 static soliton of the SU(2) Skyrme model shows a profile function dependence which is not exactly radial. We propose to quantify this with the introduction of an axially symmetric oblate ansatz parametrized by a scale factor d. We then obtain a relatively deformed bound soliton configuration with M_{B=2}/M_{B=1}=1.958. This is the first step towards to description of B>1 quantized states such as the deuteron with a non-rigid oblate ansatz where deformations due to centrifugal effects are expected to be more important.
