Perpendicular transport of cosmic rays in turbulence

Summary form only given. We address the issue of the transport of cosmic rays (CRs) perpendicular to the mean magnetic field and discuss how the diffusion changes with the CRs´ energy and the Alfvenic Mach number of the turbulence. We show that the issue of cosmic ray sub-diffusion is only important for restricted cases when the ambient turbulence is far from that suggested by numerical simulations. Moreover, we demonstrate that on small scales, the cross field transport becomes super-diffusive.
