Description

Cosmic rays propagation makes important progress in recent years. The progress implies different dark matter properties from previously expected. In the new model, the antiproton flux fits the AMS data well and no contribution from dark matter is needed and severe constraints on the dark matter annihilation are gotten. In the new model, the dark matter explanation for positron exess is relaxed by smaller annihilaiton cross section and consistent with the constraints by gamma ray observation from Fermi-LAT.
