The perpendicular diffusion coefficient (DC) plays a crucial role in the transport of low-energy cosmic ray electrons, which include a proportion of solar energetic particles, electrons originating in the Jovian magnetosphere, and electrons of galactic origin. In turn, various properties of heliospheric magnetic field turbulence have a strong influence on perpendicular DC expressions derived from theory. The effects of dynamical turbulence, as opposed to magnetostatic turbulence, have hitherto only been considered in a limited manner. This is partly due to the fact that, in deriving expressions for perpendicular DCs, the inclusion of dynamical turbulence often leads to relatively intractable integrals. Your mission, should you choose to accept it, would be to numerically integrate such expressions, derived from the random ballistic decorrelation interpretation of nonlinear guiding center theory, for different models of dynamical turbulence. These novel results will be compared with previously published perpendicular DCs derived from other theoretical approaches, and will be used to ascertain the potential effects of different dynamical turbulence models on the perpendicular transport of low-energy electrons.
