Summary and report Working Group 6: theory and simulation, for the third edition of the European Advanced Accelerator Concept Conference

The theory and simulation working group (working group 6) of the third edition of the European Advanced Accelerator Workshop has been characterized by a strong numerical connotation. Particle in cell codes have proven to be a necessary tool to finely investigate the underlying physics both for laser and plasma wakefield acceleration processes. This year, the section has been characterised by an interest in the limitation of the numerical Cherenkov effect, the mitigation of the hose-instability, start-to-end simulations and more generally on new numerical schemes and diagnostics.
