The Zero-Brane as a Soliton
Abstract:- We present an exact construction of the D0-brane as a soliton on the
worldvolume of a BPS D2-brane in the presence of a large B field.
We match the mass and spectrum of fluctuations of this soliton to the
D0-D2 conformal field theory. This spectrum includes a tachyon:
the endpoint of tachyon condensation represents the ``disappearance''
of the D0-brane, and all modes associated with it, as it dissolves in the
D2-brane. This construction thus sheds some light on issues related
to tachyon condensation.
