Abstract

The 2 + 1 dimensional O(3) nonlinear sigma model with Hopf term of strength ϑ is canonically quantized. The solitons of topological charge Q are found to have spin equal to (ϑ/2π)Q2 modulo an integer. Collective coordinate quantization in the Q = 1 sector is described and there is a discussion of the current algebra of this model.
