Remarks on excited states of affine Toda solitons

arXiv:hep-th/9608055 · doi:10.1016/S0370-2693(96)01351-2

Abstract

The identification in affine Toda field theory of the quantum particle with the lowest breather allows us to re-interpret discrete modes of excitation of solitons as breathers bound to solitons, and thus to investigate them through the proposed soliton-breather S-matrices. There are implications for the physical spectrum and for the semiclassical soliton mass corrections.
