The Energy of Scattering Solitons in the Ward Model
arXiv:hep-th/0409168 · doi:10.1098/rspa.2005.1451
Abstract
The energy density of a scattering soliton solution in Ward's integrable chiral model is shown to be instantaneously the same as the energy density of a static multi-lump solution of the $\CP^3$ sigma model. This explains the quantization of the total energy in the Ward model.
