We consider Kaluza-Klein dark matter from latticized universal dimensions. Wemotivate and investigate two different lattice models, where the models differin the choice of boundary conditions. The models reproduce relevant features ofthe continuum model for Kaluza-Klein dark matter. For the model with simpleboundary conditions, this is the case even for a model with only a few latticesites. We study the effects of the latticization on the differential flux ofpositrons from Kaluza-Klein dark matter annihilation in the galactic halo. Wefind that for different choices of the compactification radius, thedifferential positron flux rapidly converges to the continuum model results asa function of the number of lattice sites. In addition, we consider theprospects for upcoming space-based experiments such as PAMELA and AMS-02 toprobe the latticization effect.Comment: 25 pages, 9 figures, LaTeX.
