The aim of this work is the analysis of the different transport regimes related to thepropagation in the solar wind of solar energetic particles (SEPs) generated by impulsiveevents like solar flares. A numerical implementation of a Lévy random walk for parallelparticle transport is developed, which allows obtaining superdiffusive transport. Thecomparison between the flows measured by satellites and fluxes extracted from thenumerical simulation, will contribute to a deeper understanding of the mechanismsunderlying the presence of superdiffusive regimes of SEP transport in interplanetarymedium.
