On validity of perturbative quantization of the breathing mode in the Skyrme model
We present a detailed discussion of the breathing mode quantization in the Skyrme model and demonstrate that the chiral angle of the hedgehog soliton is strongly affected by the breathing motion. It was already demonstrated that the centrifugal effects seriously change chiral angle (profile function) of a rotating skyrmion [1]. At the same time the breathing mode in the Skyrme model is usually ...
متن کاملNormal Mode Spectrum of the Deuteron in the Skyrme Model
The normal mode spectrum of the deuteron in the Skyrme model is computed. We find a bound doublet mode below the pion mass, which can be related to the wellknown 90◦ scattering of two skyrmions. We also find a singlet ‘breather’ mode and another doublet above the pion mass. The qualitative pattern of the spectrum is similar to that recently found for the B = 4 multiskyrmion. The symmetries of a...
متن کاملExact vortex solutions in an extended Skyrme-Faddeev model
We construct exact vortex solutions in 3 + 1 dimensions to a theory which is an extension, due to Gies, of the Skyrme-Faddeev model, and that is believed to describe some aspects of the low energy limit of the pure SU(2) Yang-Mills theory. The exact vortices appear in a very particular sector of the theory characterized by special values of the coupling constants, and by a constraint that leads...
متن کاملFolding in the Skyrme Model
There are only three stable singularities of a differentiable map between threedimensional manifolds, namely folds, cusps and swallowtails. A Skyrme configuration is a map from space to SU2, and its singularities correspond to the points where the baryon density vanishes. In this paper we consider the singularity structure of Skyrme configurations. The Skyrme model can only be solved numericall...
متن کاملThe Skyrme Model
We review the recent developments on the Skyrme model in the context of QCD, and analyze their relevance to low-energy phenomenology. The fundamentals of chiral symmetry and PCAC are presented, and their importance in effective chiral models of the Skyrme type discussed. The nature and properties of skyrmions are thoroughly investigated, with particular stress on the basic role of the Wess—Zumi...
