Seminar
Title: Zero-Range Effective Field Theory for Resonant Dark Matter
Speaker: Dr. Hong Zhang(TUM)
Time: 10:00AM, June 4th, 2018 (Monday)
Place: Theoretical Physics Division, 319
Abstract: To solve the cusp-core problem, self-interacting dark matter (SIDM) is one of the most popular directions nowadays. In this talk, I will explain how a low-energy effective field theory (EFT) can help to constrain the properties of many high-energy SIDM models. As an example, we have set up such a Zero-Range EFT (ZREFT) for SU(2)-triplet wino and have shown its agreement with the full theory at low energy.
