Abstract
We derive an equation for the emission of classical gravitational
waves due to
quasi-elastic particle
scattering in a model with compactified extra dimensions. In
addition to previous classical studies we also
calculate additional terms that are suppressed by factors of one over
frequency times compactification radius.
From this a single formula is given which predicts
the energy loss into gravitational radiation from elastic collisions as well
in the low as in the high energy limit.
