Abstract: | Energetic particles in the heliosphere, from relatively low-energy particles which are accelerated in Corotating Interaction
Regions (CIRs) to galactic cosmic rays, are observed to propagate relatively easily in heliographic latitude. Two mechanisms
for this transport appear possible: cross-field diffusion, or, in a recent model for the heliospheric magnetic field, by direct
magnetic connection. The commonalties and differences of these two mechanisms are considered, and the need for future observations
and modeling efforts are discussed.
