Seminar 
Title: Physics of the Cosmological Collider 
Speaker: Prof.Yi Wang (王一) (Hong Kong University of Science and Technology) 
Time: 10:00AM, Dec.20th 2016 (Tuesday) 
Place: Theoretical Physics Division，319 

Abstract: We discuss how the primordial universe can be used to probe high energy physics. For this purpose, the following three topics will be covered: (1) An overview of cosmological correlation functions (non-Gaussianities). (2) Using inflation as a collider to probe the particle physics Standard Model and BSM physics. (3) Distinguishing inflation and alternative-to-inflation models from the outcome of the cosmological collider.
