Conclusion sofarIF DM particles are thermal relics from early universethey MUST annihilate with cross section=2.10 -26 cm 3 /swhich implies enormous rate of gamma raysfrom π 0 decays (produced in quark fragmentation)(Galaxy=10 40 higher rate than any accelerator)Expect large fraction of energetic Galactic gamma raysto come from DMARemaining ones from p CR +p GAS -> π 0 +X , π 0 ->2γThis means: Galactic gamma rays have 2 componentswith a shape KNOWN from the 2 BEST studied reactionsin accelerators: background known from fixed target exp.DMA known from e+e- annihilation (LEP)Wim de Boer, Karlsruhe Seminar Oxford, May. 3, 2007 6
