Microscopic laser-driven electron-positron colliders — •Carsten Müller, Karen Z. Hatsagortsyan, and Christoph H. Keitel — Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, D-69117 Heidelberg

We present an alternative concept of a laser-driven electron-positron collider [1]. High luminosities are achieved by employing a gas of positronium atoms instead of electron and positron beams. As an example, the process of muon pair creation from electron-positron annihilation in a laser field is discussed [2].
