16. Closing in on Vector Portals to Dark Matter

Patrick Foldenauer (IFT UAM-CSIC Madrid)

Vector portal interactions provide a simple and theoretically well-motivated framework for connecting dark sectors to the Standard Model. In particular, dark photons and anomaly-free gauge bosons arise naturally in extensions of the Standard Model and can play a central role in dark matter phenomenology. In this talk, I first discuss scenarios in which dark photons mediate the interactions of...

20. A General Perspective on Boosted Dark Matter from Semi-annihilation

Seongsik Kim (Chungnam National University)

We develop a systematic approach for analyzing any dark matter (DM) model that produces boosted dark matter (BDM) through semi-annihilation. We emphasize three points. First, any BDM analysis must be grounded on the correct relic density. Second, semi-annihilation intrinsically yields boosted by-products, whose contribution to indirect detection is generally non-negligible and should be...
