Coherent pair creation in linear colliders
Coherent pair creation during the collision of e+e- beams in linear colliders is examined. This includes contributions from both real and virtual photons, where the real photons are predominantly from beamstrahlung. The pair creation probability is shown to be orders of magnitude larger than the corresponding incoherent processes. The energy spectrum is also calculated where the effective threshold energy is shown to be inversely proportional to the beamstrahlung parameter . Implications of this effect on future e+e-, e, and linear colliders are discussed. © 1989 The American Physical Society.
