  We consider an initially at rest colored particle which is struck by an
ultra-relativistic nucleus. The particle is treated classically both with
respect to its motion and its color charge. The nucleus is treated as a sheet
of colored glass within the context of the Color Glass Condensate framework. We
compute both the momentum and coordinates of the struck classical particle and
the emitted radiation. Our computations generalize the classic electrodynamics
computation of the radiation of an accelerated charged particle to include the
radiation induced by the charged gluon field. This latter contribution adds to
the classic electrodynamics result and produces a gluon rapidity distribution
that is roughly constant as a function of rapidity at rapidities far from the
fragmentation region of the struck particles. These computations may form the
basis of a first principles treatment for the initial conditions for the
evolution of matter produced in the fragmentation region of asymptotically high
energy collisions.
