Title:Role of dark Higgs boson in (astro) particle physics and cosmology
Speaker：Prof. Pyungwon Ko
Affiliation: School of Physics, Korea Institute for Advanced Study

Place: Room 203, South Tian Jia Bing Building
Abstract:
In this talk, I will describe electroweak scale dark matter and dark force mediators, focusing on massive dark photon and dark Higgs boson. I will contrast two scenarios, dark photon without and with dark Higgs boson, and show that dark Higgs boson can solve theoretical and phenomenological problems of DM models without dark Higgs boson.
