Inflation as a Cosmological Collider
Yi Wang, Hong Kong University of Science and Technology,

From three and four-point correlation functions of cosmological density fluctuations, one can get information about the spin, mass, width and CP information of heavy particles in the inflationary era of the universe. This approach is known as the cosmological collider physics. Here we talk about cosmological collider physics and its phenomenology such as particle physics standard model and BSM physics. We also show that the same physical process can be used as a quantum primordial standard clock to measure the expansion history of the primordial universe.
