Caveats • Implicitly assumed that LSP constitutes all of dark matter • Assumed radiation domination in post-inflation era. No clear evidence between freeze-out+BBN that this is the case (t eq changes). • Examples of non-standard cosmology that would change the prediction: • Extra degrees of freedom • Low reheating temperature • Extra dimensional models • Anisotropic cosmologies • Non-thermal production of neutralinos (late decays) SUSY Dark Matter and Colliders B.C.
