چکیده

We show that the Skyrme theory possesses a submodel with an infinite number of local conserved currents. The Skyrmions of unit topological charge belong to such integrable sector of the theory. The constraints leading to the submodel explore a decomposition of SU (2) with a complex field parametrizing the symmetric space SU (2)/U (1) and a real field in the direction of U (1). The higher charges configurations constructed through rational map Ansätze, are particular solutions of the constraints. Our results open ways to the development of exact methods, compensating for the non-existence of a BPS type sector in the Skyrme theory.

Nuclear Matter Aspects of Skyrmions

As an alternative approach to the infinite-array description of dense matter in the Skyrme model, we report about the properties of a single skyrmion on a compact 3-sphere of finite radius. The density of this matter can be increased by decreasing the hypersphere radius. As in the array calculations one encounters a transition to a distinct high density phase characterized by a delocalization i...

Normal 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...

2 00 4 Symmetries of generalized soliton models and submodels on target space

Some physically relevant non-linear models with solitons, which have target space S 2 , are known to have submodels with infinitly many conservation laws defined by the eikonal equation. Here we calculate all the symmetries of these models and their submodels by the prolongation method. We find that for some models, like the Baby Skyrme model, the submodels have additional symmetries, whereas f...

Magnetic moments of heavy baryons in the Skyrme model

We calculate the magnetic moments of heavy baryons in the Skyrme model in the limit of infinite heavy quark mass. We show that the Skyrme model yields the same limit as the nonrelativistic quark model when heavy vector mesons are treated properly. The essential role of the magnetic moment coupling terms in the electromagnetic interactions of heavy mesons is discussed. Typeset using REVTEX ∗On l...

Multi-Skyrmions with Vector Mesons

It is known that including vector mesons stabilizes the size of a Skyrmion without the need for a Skyrme term. This paper provides the first results for static multiSkyrmions in such a theory. The rational map ansatz is used to investigate multiSkyrmions in a theory which includes the ω vector meson and has no Skyrme term. Bound states with baryon numbers two, three and four are found, which ha...
