Signatures for strongfield QED physics in the quantum limit of beamstrahlung
Abstract
Collisions between round ultrarelativistic leptonic beams are proposed to probe strongfield quantum electrodynamics (SFQED) in the quantum limit of beamstrahlung. The collective radiation spectrum from a leptonic collision is derived. A characteristic spectral peak close to the beam energy is identified, as a signature predicted by SFQED theory. The dependences of the spectral peak and beamstrahlung on the collision parameters are determined, paving the way to experimentally verify SFQED. Ultrashort, ultrabright, and highluminosity colliding gammaray beams are generated. The theoretical results are confirmed by selfconsistent 3dimensional QED particleincell simulations.
