- Effective Field Theory of Light Nuclei
- Time: 4:00 pm
- Place: 4274 Chamberlin Hall
- Speaker: Bira van Kolck, University of Arizona
- Abstract: Nucleons in light nuclei have binding momenta smaller than the pion mass. In this energy regime, strong interactions can be described by effective field theories (EFTs) where all nuclear interactions are of contact type. I will discuss some of the features of these EFTs such as unusual renormalization leading to limit cycles, universal behavior in three-body systems, and a surprising amount of fine-tuning.
