Effects of laterally shifted bunch collisions on QED processes — •Marko Filipovic¹, Christoph Baumann¹, Alexander Pukhov¹, Alexander Samsonov², and Igor Kostyukov² — ¹Heinrich-Heine-Universität, Düsseldorf, Germany — ²Institute of Applied RAS, Nizhny Novgorod, Russia

The collision of ultrarelativsitic electron bunches is a promising opportunity to study quantum electrodynamic effects in extreme fields and densities, this includes quantum photon emission and pair production. It was even conjectured that the interaction of light and matter can become fully non-perturbative. In this talk, the results of three-dimensional particle-in-simulations will be presented. First, the basic idea of the fully non-perturbative particle collider [1] will be recalled. Subsequently the configuration will be modified by considering the collision of two laterally shifted bunches. In detail, the impact on photon and pair yields through the modification will be compared and assessed by previous Beam-Beam collision estimates. Finally, the influence of longer bunches in the collider configurations will be considered.
