Аннотация:A classical computation of gravitational bremsstrahlung in ultra-planckian
collisions of massive point particles is presented in an arbitrary number d of toroidal or non-compact extra dimensions. Our method generalizes the post-linear formalism of General
Relativity to the multidimensional case. The total emitted energy, as well as its angular
and frequency distribution are discussed in detail. The domain of validity of the classical
result is discussed. Finally, it is shown that within the region of validity of our approach
the efficiency can obtain unnatural values greater than one, which is interpreted to mean
that the peripheral ultra-planckian collisions should be strongly radiation damped.
