Physics and Astronomy Colloquium

14 billion years in the life of a dark matter particle

Presented by Tongyan Lin, UC San Diego

Dark matter is the dominant form of matter in the universe, and has been observed through its gravitational pull on stars and galaxies. However, the fundamental particle physics underlying dark matter is unknown. I will describe how we could shed light on this puzzle by following the journey of a dark matter particle, from its creation in the Big Bang 14 billion years ago, to its interactions when the universe was ~380,000 years old and the microwave background light was being formed, and finally a peek into the future when such a dark matter particle could scatter off a crystal target in proposed direct detection experiments.
