Abstract
We examine the energetics of -balls in Maxwell-Chern-Simons theory in two space dimensions. Whereas gauged -balls are unallowed in this dimension in the absence of a Chern-Simons term due to a divergent electromagnetic energy, the addition of a Chern-Simons term introduces a gauge field mass and renders finite the otherwise-divergent electromagnetic energy of the -ball. Similar to the case of gauged -balls, Maxwell-Chern-Simons -balls have a maximal charge. The properties of these solitons are studied as a function of the parameters of the model considered, using a numerical technique known as relaxation. The results are compared to expectations based on qualitative arguments.
