Abstract: 

The longstanding puzzles of matter-antimatter asymmetry and dark matter point to the need for physics beyond the Standard Model. A first-order phase transition in the early Universe could provide the necessary conditions for baryogenesis, the generation of dark matter, and even primordial black holes. These new physics mechanisms can be probed in current or near-future experiments involving colliders, gravitational waves, and direct or indirect detection of dark matter. This talk will discuss the basics of cosmic first-order phase transitions and recent developments in relevant new physics mechanisms.
