The aim of this work is the analysis of the different transport regimes related to the propagation in the solar wind of solar energetic particles (SEPs) generated by impulsive events like solar flares. A numerical implementation of a Lévy random walk for parallel particle transport is developed, which allows obtaining superdiffusive transport. The comparison between the flows measured by satellites and fluxes extracted from the numerical simulation, will contribute to a deeper understanding of the mechanisms underlying the presence of superdiffusive regimes of SEP transport in interplanetary medium.
