(In)direct Detection of Boosted Dark Matter

Understand

We initiate the study of novel thermal dark matter (DM) scenarios where present-day annihilation of DM in the galactic center produces boosted stable particles in the dark sector.

• These stable particles are typically a subdominant DM component, but because they are produced with a large Lorentz boost in this process, they can be detected in large volume terrestrial experiments via neutral-current-like interactions with electrons or nuclei.
• This novel DM signal thus combines the production mechanism associated with indirect detection experiments (i.e.
• galactic DM annihilation) with the detection mechanism associated with direct detection experiments (i.e.
