Constraining heavy dark matter with cosmic-ray antiprotons

Understand

Cosmic-ray observations provide a powerful probe of dark matter annihilation in the Galaxy.

• In this paper we derive constraints on heavy dark matter from the recent precise AMS-02 antiproton data.
• We consider all possible annihilation channels into pairs of standard model particles.
• Furthermore, we interpret our results in the context of minimal dark matter, including higgsino, wino and quintuplet dark matter.
