GRAVITATIONAL BEAMSTRAHLUNG

Abstract

A semiclassical formalism of gravitational radiation from the collision of high energy e+e− beams is derived. The charged particles interact with the strong collective EM field of the oncoming beam and emit beamstrahlung. We show that these photons would couple to the same EM field and resonantly excite gravitational waves with much higher frequencies than those from astrophysical signals. We examine several physical examples and show that there is a finite probability for emitting such “gravitons”.
