- Echoes of Supersymmetry: Baryon Asymmetry, Relic Q-balls, and Gravity Waves
- Time: 4:00 pm
- Place: 4274 Chamberlin
- Speaker: Alex Kusenko, UCLA
- Abstract: If supersymmetry is realized in nature, even at some very high energy scales, it has important cosmological consequences. A generic prediction of supersymmetry is the flat directions in the potential, along which a scalar condensate can form at the end of inflation. This condensate is generically unstable; its evolution and its fragmentation into Q-balls can generate the baryon asymmetry, dark matter, and the gravity waves that can be observed by upcoming detectors.
