- Chaos & Complex Systems Seminar
- 2016 Polling in Nation and State: A scorecard
- Time: 12:05 pm
- Place: 4274 Chamberlin (refreshments will be served)
- Speaker: Charles Franklin, Law and Public Policy and Director of the Marquette University Law School Poll
- Abstract: How did the pre-election polls of 2016, at both national and state levels, perform? What did we learn about the dynamics of the campaign and the issues affecting public polling? How accurate were the polls and were some methods better than others?
- Host: Clint Sprott
- Theory Seminar (High Energy/Cosmology)
- Search For Dark Matter In Terms of Dark Bound States
- Time: 3:30 pm
- Place: 5280 Chamberlin
- Speaker: Yue Zhang, Northwestern
- Abstract: Understanding the nature of dark matter is an open question of central importance to particle physics and cosmology. In this talk, I discuss a model where the dark matter is a fermion charged under a dark U(1) gauge symmetry and its interactions are mediated by a massive dark photon. I will summarize the current status in the search for such a dark sector. The main focus of this talk is on the non-perturbative effects in particular dark matter bound states, which could have strong impact on the interpretation of existing experimental results and lead to new channels for the future search.
