  We present the first numerical study of the full dynamics of a braneworld
scenario, working within the framework of the single brane model of Randall and
Sundrum (RSII). In particular, we study the process of gravitational collapse
driven by a massless scalar field which is confined to the brane. Imposing
spherical symmetry on the brane, we show that the evolutions of sufficiently
strong initial configurations of the scalar field result in black holes that
have finite extension into the bulk. Furthermore, we find preliminary evidence
that the black holes generated form a unique sequence, irrespective of the
details of the initial data. The black hole solutions we obtain from dynamical
evolutions are consistent with those previously computed from a static vacuum
ansatz.
