  The problem of computing the effective nonrelativistic potential $U_{D}$ for
the interaction of charged scalar bosons within the context of D-dimensional
electromagnetism with a cutoff, is reduced to quadratures. It is shown that
$U_3$ cannot bind a pair of identical charged scalar bosons; nevertheless,
numerical calculations indicate that boson-boson bound states do exist in the
framework of three-dimensional higher-derivative electromagnetism augmented by
a topological Chern-Simons term.
