Abstract: | Cross field diffusion of energetic particles (cosmic rays) in a two-dimensional static magnetic field turbulence is studied
performing test particle simulations. Qualitatively different diffusion processes are observed depending on the ratio of Larmor
radius (ρ) to the correlation length (λ) of the magnetic field fluctuations. The diffusion is found to be composed of several
regimes with distinct statistical properties, which can be characterized using Levy statistics.
