Abstract: We consider the collective quantization of translational degrees of freedom of the hedgehog soliton in the Nambu-Iona-Lasinio Model, We show explicitly that for an O(4)-invariant regularization scheme in Euclidean space-time the translational mas obtained in the penurbative pushing model coincides with the static mas. Zeropoint energies for translation and rotation are evaluated numerically. The nucleon mass appears to be around 900 MeV.
