IAS Program on Particle Theory

Exotic Energy Injection in the Early Universe


The production of electromagnetically interacting particles in the early Universe is a generic prediction of many extensions of both the standard models of particle physics and cosmology. In this talk, the speaker will give an overview of recent progress in understanding how injected particles deposit their energy into regular matter, and highlight some novel signatures of new physics that are well within current and near-future experimental reach.


About the Speaker
