Query: Maxwell-Chern-Simons Q-balls   We examine the energetics of $Q$-balls in Maxwell-Chern-Simons theory in two
space dimensions. Whereas gauged $Q$-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 $Q$-ball. Similar
to the case of gauged $Q$-balls, Maxwell-Chern-Simons $Q$-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.
