Neutralino Dark Matter from Indirect Detection Revisited

Understand

We revisit indirect detection possibilities for neutralino dark matter, emphasizing the complementary roles of different approaches.

• While thermally produced dark matter often requires large astrophysical "boost factors" to observe antimatter signals, the physically motivated alternative of non-thermal dark matter can naturally provide interesting signals, for example from light wino or Higgsino dark matter.
• After a brief review of cosmic ray propagation, we discuss signals for positrons, antiprotons, synchrotron radiation and gamma rays from wino annihilation in the galactic halo, and examine their phenomenology.
• For pure wino dark matter relevant to the LHC, PAMELA and GLAST should report signals.
