Abstract

The authors investigate the infrared behaviour of gravitational radiation emitted from the scattering of massless particles at very high energies. By employing a semi-classical method -- eikonal approach -- they compute subleading corrections to the spectrum of gravitational radiation emitted, and find that these corrections give rise to a local maximum at frequency \ensuremathω~0.5/b, where b is the impact parameter of the scattering.
