Astrophysical signatures of axino dark matter

Presented by Mr. Seng Pei LIEW on 25 Jul 2014 from 14:50 to 15:10
Type: Particle Cosmology
Track: Particle Cosmology


Axino interacts weakly with ordinary matter and can be a good candidate of dark matter. In the case where R-parity is violated, axino dark matter decays slowly and can have interesting signatures in the form of cosmic rays. Here, we show two concrete examples of decaying axino dark matter that can explain the recently observed astrophysical anomalies: 130 GeV gamma-ray line from the Galactic Center, and 7 keV X-ray line from galaxy clusters. This talk is based on [1301.7536] and [1403.6621].
