Solitons with Isospin
arXiv:hep-th/0405182 · doi:10.1016/j.nuclphysb.2005.02.024
Abstract
We study the symmetries of the soliton spectrum of a pair of T-dual integrable models, invariant under global transformations. They represent an integrable perturbation of the reduced Gepner parafermions, based on certain gauged SL(3) - WZW model. Their (semiclassical) topological soliton solutions, carrying isospin and belonging to the root of unity representations of q-deformed - algebra are obtained. We derive the semiclassical particle spectrum of these models, which is further used to prove their T-duality properties.
