Abstract
We present the energy spectra of the fluxes of positrons, anti-protons and photons generated by Dark Matter annihilations in our galaxy, as univocally predicted by the model of Minimal Dark Matter. Due to multi-TeV masses and to the Sommerfeld enhancement of the annihilation cross section, distinctive signals are generated above the background, even with a modest astrophysical boost factor, in the range of energies soon to be explored by cosmic ray experiments.
16 pages, 6 figures, 3 tables of fit parameters. v3: in an addendum at page 17 we show that the Minimal Dark Matter prediction agrees with the anomaly in the positron spectrum announced by the PAMELA collaboration
