简介: |
In hidden sector models, dark matter particles could annihilate into light and metastable mediators, which subsequently decay far away from where they are produced. I will talk about how the indirect signatures in this scenario are altered with respect to the situation of conventional WIMP, as well as how this scenario may (or may not) be able to explain the observed PAMALA/AMS-02 positron excess in cosmic rays. |
