Astroparticle Physics and Colliders

Abstract

In this talk I discuss the interplay between collider physics and four topics of astro-particle physics: neutrino oscillations, electroweak baryogenesis, LSP Dark Matter, and ultra-high energy cosmic rays (UHECR). Some astrophysical scenarios can (only) be tested decisively at colliders. In other cases input from collider experiments is required to sharpen predictions for future astro--particle physics experiments, e.g. for the LSP detection rate or the UHECR spectrum in top--down models.
