Casimir corrections in the bound state soliton model

Abstract

We consider the one-loop corrections to the SU(3) skyrmion mass within the bound state soliton approach. We show that the standard SU(3) renormalization scheme is not appropiate within this framework and propose to use an alternative one based on SU(2). For physical meson masses and decay constants the resulting Casimir correction turns out to be rather scale-independent and leads to an acceptable estimate of the nucleon mass.
