Relieving the Tension between Dark Matter Production of High-energy Cosmic Antiparticles and FERMI/LAT Constraint on Isotropic Diffuse Gamma-ray Background
Abstract
The dark matter explanation of both cosmic ray positron and antiproton excesses, seen by PAMELA and recently confirmed by AMS-02, inevitably faces the contradiction with the latest FERMI/LAT data on isotropic diffuse gamma-ray background (IGRB). Here we discuss a possible solution to this problem, based on the accumulation of self-interacting dark matter component in the Galactic disk. For the same purpose, the mechanism of high-energy antiparticle production in the collisions of high-energy particles with matter can also be suggested.
