Picture of DM distribution at the galaxy 1. 2. Dark Matter Detection The last result is given by CDMS. The null result give stronger constraints on the SUSY parameters. The DAMA region is almost entirely excluded. There are great progress in dark matter direct detection. New experiments are going to take data. Dark Matter Detection I. Some astrophysics observations can not be explained by the canonical physics. They may indicate the signal of DM, however, no conclusion can be drawn now. I.

There is an excess above 8 GeV, which can be explained by dark matter annihilation. II. One of such experiments is the HEAT. There is an excess above 8 GeV, which can be explained by dark matter annihilation. III. Sensitivity will be greatly improved at Pamela and AMS02. Dark Matter Detection Based on local cosmic ray spectrum gives consistent gamma ray spectrum in 30 MeV~500 MeV, above 1 GeV there is an excess. Based on local cosmic ray spectrum gives consistent gamma ray spectrum in 30 MeV~500 MeV, above 1 GeV there is an excess. Taking the contribution from dark matter annihilation into account the data can be well explained. Taking the contribution from dark matter annihilation into account the data can be well explained.
