Indirect Searches for Dark Matter with AMS-02

Understand

AMS-02 is a multi-purpose spectrometer with superconducting magnet, and is designed for 3 years of data taking aboard the International Space Station.

• Its high performance regarding particle identification and energy measurement will allow performing indirect searches for dark matter (DM) in different channels simultaneously: gamma rays, positrons and antiprotons.
• AMS-02 sensitivity to those signals are presented and --provided the positron excess is due to DM signal-- it is shown that it allows to probe new physics models in detail.
• Its high sensitivity could even be a unique opportunity to reach the Majorana nature of the DM particle through final state polarization effects.
