Observing CDM via the WIMP LSP

Assuming that the WIMPS once were in thermal equilibrium, one finds that the relic WIMP froze out at 

Accelerator limits set a lower bound, and the inclusion of the extra degrees of freedom from coannihilations sets an upper bound. Direct searches may also independently set a model-dependent lower bound. 

Indirect searches via halo annihilations of the LSP into 7, p,e+,ir have hitherto been inconclusive. There are hints of an anomalous feature in the high energy e+ spectrum. However halo detection of e+ requires dumpiness of order
