Scalar Dark Matter: Direct vs. Indirect Detection

Understand

We revisit the simplest model for dark matter.

• In this context the dark matter candidate is a real scalar field which interacts with the Standard Model particles through the Higgs portal.
• We discuss the relic density constraints as well as the predictions for direct and indirect detection.
• The final state radiation processes are investigated in order to understand the visibility of the gamma lines from dark matter annihilation.
